Range of application of 304 stainless steel 304 stainless steel is one of the most widely used chromium-nickel stainless steel, as a widely used steel, has good corrosion resistance, heat resistance, low temperature strength and mechanical properties;Good thermal processing property such as punching and bending, no hardening phenomenon of heat treatment (using temperature -196℃~800℃).Corrosion resistance in the atmosphere, if it is industrial atmosphere or heavily polluted areas, it is necessary to clean in time to avoid corrosion.Suitable for food processing, storage and transportation.It has good machining performance and weldability.Plate heat exchanger, bellows, household products (Class 1, 2 tableware, cabinets, indoor pipelines, water heaters, boilers, bathtubs), auto parts (windshield wipers, mufflers, mold products), medical appliances, building materials, chemistry, food industry, agriculture, Marine parts, etc.304 stainless steel is food grade stainless steel recognized by the country. Most of the requirements are to maintain the original appearance of the building for a long time.In determining the type of stainless steel to be selected, the main consideration is the required aesthetic standards, the corrosive atmosphere and the cleaning system to be used.However, other applications increasingly seek only structural integrity or water impermeability.For example, the roof and side walls of an industrial building.In these applications, construction cost to the owner may be more important than aesthetics, even if the surface is not very clean.304 stainless steel works well in dry indoor environments.However, in the country and the city to maintain its appearance outdoors, it needs to be washed regularly.In heavily polluted industrial and coastal areas, the

What is 304 stainless steel In our previous company news that we introduced many features of 304 stainless steel so today I will introduce what is 304 stainless steel to you. 304 stainless steel is a common material in stainless steel, density of 7.93 g/cm³;Also known in the industry as 18/8 stainless steel, meaning contains more than 18% chromium and more than 8% nickel;High temperature resistance 800℃, has the characteristics of good processing performance, high toughness, widely used in industrial and furniture decoration industry and food and medical industry.But it should be noted that food grade 304 stainless steel compared with ordinary 304 stainless steel, its content index is more strict.For example: the international definition of 304 stainless steel is mainly chromium 18%-20% nickel 8%-10%, but food grade 304 stainless steel is chromium 18% and nickel 8%, allow a certain range of fluctuations, and limit the content of various heavy metals.In other words, 304 stainless steel is not necessarily food grade 304 stainless steel There are 06Cr19Ni10, SUS304 in the common labeling method on the market, where 06Cr19Ni10 generally represents the national standard production, 304 generally represents the ASTM standard production, SUS304 represents the Japanese standard production. 304 is a kind of universal stainless steel, which is widely used in the production of equipment and parts requiring good comprehensive performance (corrosion resistance and mo

The main difference between food grade stainless steel and stainless steel is: Food grade 304 stainless steel is a grade of stainless steel produced according to ASTM standards in the United States.The most important elements in 304 are Ni and Cr, but not limited to these two elements.Specific requirements are specified by product standards.Industry common judgment that as long as the Ni content is greater than 8%, Cr content is greater than 18%, it can be considered 304 stainless steel. Stainless Steel (Stainless Steel) is short for Stainless acid resistant Steel, Stainless Steel refers to air, steam, water and other weak corrosive medium and acid, alkali, salt and other chemical corrosive medium corrosion of Steel, also known as Stainless acid resistant Steel.The corrosion resistance of stainless steel depends on the alloying elements contained in the steel. The main alloying element in stainless steel is Cr (chromium). Only when the content of Cr reaches a certain value, the steel has corrosion resistance.Therefore, stainless steel generally Cr (chromium) content of at least 10.5%.Stainless steel also contains Ni, Ti, Mn, N, Nb, Mo, Si, Cu and other elements. 304 stainless steel is a common material in stainless steel, density of 7.93g /cm3, the industry is also called 18/8 stainless steel.High temperature resistance 800℃, has the characteristics of good processing performance, high toughness, widely used in industrial and furniture decoration industry and food and medical industry. 304 is a kind of universal stainless steel, which is widely used

Why 304 stainless steel is called food grade stainless steel You must be very familiar with 304 stainless steel, we are Lane Joy and we are a factory located in Shenzhen and we production of a variety of 304 stainless steel products for more than 13 years such as Cooling Rack, Baking Rack, Cooking Rack, Smoking Rack,Draining Rack,Barbecue Grill Grate, Grill Mesh, Cooking Grid, Pull Out Cabinet Organizer,Fruit & Vegetable Basket. And our products are suitable for a variety of environments, so in thousands of households can often see their figure, therefore, 304 stainless steel also has a name called food grade stainless steel. Many people do not understand why 304 stainless steel is known as food grade stainless steel, then we will do a simple science for you, why 304 stainless steel is known as food grade reasons. First of all, we need to understand that there are a lot of weak acid and alkaline substances in the food processing plant. Over time, these substances will produce corrosion on the metal, and 304 stainless steel itself has good corrosion resistance, but the chemical reaction with acid and base will still decompose various prices of "chromium", toxic.Moreover, it is required to limit the content of various alloy impurities such as lead and cadmium. Stainless steel internal mixed with chromium, nickel element, this element is the key to rust, if the nickel and chromium content is high, the stronger the corrosion protection functio

Why use 304 food grade stainless steel Stainless steel is closely related to our life. POTS, electric kettles and sinks used in our daily life are made of stainless steel, and even some food and beverage processing equipment, and medical equipment that we can't see will also be used in stainless steel. In order to achieve toughness and stiffness and not rust requirements, stainless steel is doped with many other metal elements such as:Manganese, nickel, chromium, lead, etc., and many of our daily food is a weak acid, such as fruit, vinegar, green vegetables, these foods in the process of long-term contact with the stainless steel can cause corrosion of stainless steel, and toxicity of heavy metal ions, in the long run, it will cause great hidden danger to our health. In order to resist inferior stainless steel flooding the market, cause great harm to our health, the country issued the "People's Republic of China national standard/stainless steel food container health standards", and strict requirements of the major manufacturers in accordance with this standard to produce qualified products. Food grade stainless steel refers to the stainless steel material in accordance with the "People's Republic of China National Standards/stainless steel utensils and containers Health standards" GB 9684-2011. Food grade stainless steel refers to the food mechanical contact with the food part, must meet certain food safety requirements.Because the food production process to use a lot of acid and alkali, and stainless steel contains chromium, unqualified stainless steel,

304 stainless steel product standard The most important elements in 304 are Ni and Cr, but not limited to these two elements.Specific requirements are specified by product standards.Industry common judgment that as long as the Ni content is greater than 8%, Cr content is greater than 18%, it can be considered 304 stainless steel.This is why the industry will be called 18/8 stainless steel reasons.In fact, the relevant product standards for 304 have very clear provisions, and these product standards for different shapes of stainless steel and there are some differences.Here are some common product standards and tests. In order to determine whether a material is 304 stainless steel, must meet the requirements of each element in the product standard, as long as there is a does not meet, can not be called 304 stainless steel. Food grade stainless steel refers to in line with the "People's Republic of China national standard/stainless steel container health standard" GB 9684-88 provisions of stainless steel material, its lead content is much lower than the general stainless steel. Food grade stainless steel refers to the food mechanical contact with the food part, must meet certain food safety requirements.Because the food production process to use a lot of acid and alkali, and stainless steel contains chromium, unqualified stainless steel, will dissolve a variety of prices of chromium, toxic;Moreover, it is required to limit the content of various alloy impurities such as lead and cadmium.So choose the right products with right material is extremely important. Please kindly note that all

Correct test method for 304 stainless steel With the development of science and technology, our modern quality requirements for buildings are also higher and higher.The quality of a building is mainly its structure and materials.The structure is designed by a special designer, and the materials are free to choose.Stainless steel is the most widely used building in modern times, and there are many kinds and models of it.The most popular is 304 stainless steel. Today, we bring you 304 stainless steel and how to distinguish between true and false. The details as below: Tools/Materials a, professional testing potion b, the magnet STEPS: 1, the need for professional help, professionals can rely on the color and smoothness of the steel surface to distinguish the true and false steel. 2, special steel inspection liquid medicine, this liquid medicine in general hardware stores can be purchased, so we can not worry about the problem of supply.304 stainless steel, it is tested by the liquid medicine in 3-5 minutes will not change color.In addition, the 201 stainless steel potion will turn dark brown red in an instant, the 202 stainless steel potion will turn light brown red in 5 seconds, and the 301 stainless steel potion will turn light brick red in 1-2 minutes.

As we all know, the 304 stainless steel products we use daily will appear rust spots for a long time even after proper cleaning and care.So a good method to remove rust is particularly important. Next, let's talk about how to remove rust spots of stainless steel products: Determine the cause of corrosion.Whether it is due to product wear, sediment, water, or chloride, it is especially important to determine the cause of corrosion so that your care and cleaning methods can be corrected to avoid future recurrence of corrosion. Use a scratch-free pad to remove rust from the product.Do not apply any moisture or chemicals to the mat, only on stainless steel products.Gently scrub clean with the texture of stainless steel. Pro tip: Test it on a small, concealed stainless steel spot until you "feel" the pressure to apply. Use a cleaning paste or powder and multifunctional cleaning powder. Wipe the corroded area with a soft cloth or microfiber towel to avoid scratching the surface. Then wet a separate area of the towel to remove excess paste or powder. Finally be sure to use a stainless steel safety polish like Spiffy Shine frequently to help remove any corrosive elements from the stainless steel product and allow the passivation layer to recover.Remember to thoroughly wash all surfaces that come into contact with food after using Spiffy Shine in the kitchen. Although stainless steel product has excellent corrosion resistance, compatibility, and in a wide range of characteristics s

Despite the strength and environmental resistance of stainless steel products, all grades of steel require some level of maintenance.Pay attention to corrosion and damage when using.Otherwise, the material will eventually reach the point where it needs to be replaced.So it is particularly important to know how to maintain stainless steel products. Next, let's talk about how to maintain stainless steel products. Regular cleaning: As with many types of alloys, regular cleaning is a must and very important.For basic daily cleaning, simply apply warm soap and water to the metal surface with a sponge.You can also use a mild detergent.For more serious stains, you may need to purchase special steel cleaners and polish.Just be sure to avoid powders and other corrosive materials as they can scratch and cause rust. Avoid harsh chemicals: In general, avoid using acidic cleaners or diluting them with water.The use of too much acid will dull the surface of steel.If you use acid or chloride, be sure to rinse with warm water immediately after application.Also, avoid using solvents in small Spaces or environments with fire, as these chemicals are highly flammable. Stay away from metal brushes: While scrubbing stubborn residue with steel wool or other metal brushes may seem effective, they can scratch the surface of the steel.For all grades of stainless steel, scratches can allow rust and bacteria to build up.This is especially important if you use steel in food processing. Cover up: When you are not using these stainless steel products, cover it with a sheet or tarp if possible.This will prevent any debris from falling on it and keep it clean

From the smallest screw to the largest skyscraper, stainless steel is an essential part in our modern life. The strength, corrosion resistance and low maintenance of stainless steel make it ideal for a wide range of applications.It has a long life cycle and is 100% recyclable. There are more than 150 grades of stainless steel, 15 of which are commonly used in everyday applications.Stainless steel comes in a variety of forms, including a variety of tableware and kitchen items used in industrial and domestic Settings. Stainless steel is widely used in kitchen fittings, cutlery and cookware.Less tough steel grades are used to make blades with sharp edges.More toughness grades of steel are used in items that must be shaped, such as various cookware, grill grates, sinks and saucepans.Stainless steel is also used to finish refrigerators, freezers, countertops and dishwashers. Stainless steel is an ideal material for food production and storage because it does not affect the flavor of food.Corrosion resistance of stainless steel is important because some foods, like orange juice, can be acidic.In addition, stainless steel is easy to clean and helps prevent harmful bacteria from growing. Stainless steel is also important in ice cream production because it allows the use of strong antibacterial cleaning products. The most common use of stainless steel is on food and catering that our factory manufacture all kinds of kitchenware such as Grill Grate, Gri

Stainless steel kitchenware belongs to metal products, in using process, need not worry about the problem of fir

One of the main reasons why people choose to use stainless steel product is due to its advantages, and the most popular one is its corrosion resistance. The fact that stainless steel has high and low temperature resistance means that it can be used in many applications and many industries. Some stainless steels will maintain high strength at high temperatures, while others will actually maintain high mechanical properties at low temperatures. Sheer strength is one of the main reasons why people use stainless steel. The strength is demonstrated in the use of the building and construction industry. And the beauty of stainless steel also makes it a popular choice for many people. Stainless steel is available in a range of surface finishes and the fact that it can also be polished makes it aesthetically pleasing to the eye. Because its long life cycle makes it perfect for construction, it is ahead of other products, because it will last longer than many products. Combined with the fact that stainless steel is easy to maintain, it is the lowest cost option in a life cycle cost comparison. As it is an environmentally friendly material because it is 100% recyclable any new stainless steel normally contains around 50-80% recycled material. Stainless steel is undoubtedly a valuable material which has many uses within a whole range of industries and without it we would have to use other materials which wouldn`t be as effective. To sum up, these are the reasons why people like to use stainless steel products. Lane Joy Technology Co. Ltd is a factory that

The decisive role of chromium in stainless steel: There is only one element that determines the properties of stainless steel, which is chromium, and each stainless steel contains a certain amount of chromium. To date, there is no stainless steel without chromium. The fundamental reason why chromium has become the main element that determines the properties of stainless steel is that adding chromium as an alloying element to the steel promotes the internal contradictory movement to the development of the aspect that is conducive to resisting corrosion damage. This change can be explained from the following aspects: ①Cr increases the electrode potential of iron-based solid solution, ②Cr absorbs iron electrons to passivate iron. Passivation is a phenomenon in which the corrosion resistance of metals and alloys is improved due to the blocked anodic reaction. There are many theories of passivation of constituent metals and alloys, mainly including thin film theory, adsorption theory and electron arrangement theory.

The physical properties of stainless steel are mainly expressed in the following aspects: ①.Thermal expansion coefficient: changes in material quality elements due to temperature changes. The expansion coefficient is the slope of the expansion-temperature curve, the instantaneous expansion coefficient is the slope at a specific temperature, and the average slope between two specified temperatures is the average thermal expansion coefficient. The expansion coefficient can be expressed by volume or length, usually expressed by length. ②. Density: The density of a substance is the mass of the substance per unit volume, and the unit is kg/m³. ③.Modulus of elasticity: When the force applied to the two ends of the rib per unit length can cause the unit change in the length of the object, the force required per unit area is called the modulus of elasticity. The unit is N/㎡. ④. Resistivity: The resistance measured between the two opposite sides of the cube material per unit length, expressed in Ω·m or Ω·m㎡/m. ⑤. Magnetic permeability: dimensionless coefficient, indicating the degree to which the material is easily magnetized, and is the ratio of the magnetic induction intensity to the magnetic field intensity. ⑥. Melting temperature range: Determine the temperature at which the alloy begins to solidify and solidifies. ⑦. Specific heat capacity: the heat required to change the temperature of a unit mass of a substance by 1 degree. The specific heat capacity is the same value in both the imperial and CGs systems because the unit of heat (Biu or cal) depends on the amoun

Austenitic-ferritic duplex stainless steels are stainless steels in which austenitic and ferritic structures account for about half of each. In the case of low C content, the Cr content is 18%~28%, and the Ni content is 3%~10%. Some steels also contain Mo, Cu, Si, Nb, Ti, N and other alloying elements. This type of steel has both the characteristics of austenitic and ferritic stainless steel. Compared with ferrite, it has higher plasticity and toughness, no room temperature brittleness, significantly improved intergranular corrosion resistance and welding performance, while maintaining iron The 475 ℃ brittleness of the element stainless steel, the high thermal conductivity and the superplasticity. Compared with austenitic stainless steel, it has high strength and significantly improved resistance to intergranular corrosion and chloride stress corrosion. Duplex stainless steel has excellent pitting corrosion resistance and is also a nickel-saving stainless steel.

Stainless steel with austenitic structure at normal temperature. When the steel contains about 18% Cr, 8%~10% Ni, and about 0.1% C, it has a stable austenite structure. Austenitic chromium-nickel stainless steel includes the well-known 18Cr-8Ni steel and high Cr-Ni series steel developed on this basis by increasing the content of Cr and Ni and adding Mo, Cu, Si, Nb, Ti and other elements. Austenitic stainless steel is non-magnetic and has high toughness and plasticity, but its strength is low, it is impossible to strengthen it through transformation, and it can only be strengthened through cold working. Such as adding S, Ca, Se, Te and other elements, it has good machinability. In addition to the corrosion resistance of oxidizing acid medium, this kind of steel can also resist the corrosion of sulfuric acid, phosphoric acid, formic acid, acetic acid, urea, etc. if it contains elements such as Mo and Cu. If the carbon content in this type of steel is less than 0.03% or contains Ti and Ni, its resistance to intergranular corrosion can be significantly improved. High-silicon austenitic stainless steel with concentrated nitric acid has good corrosion resistance. Due to the comprehensive and good comprehensive properties of austenitic stainless steel, it has been widely used in various industries.
