304 stainless steel is a common material in stainless steel, density of 7.93 g/cm3, also known as 18/8 stainless steel.High temperature resistance 800℃, with good processing performance, high toughness, widely used in the industry and furniture decoration industry and food and medical industry.
Common labeling methods on the market include 0Cr18Ni9 and SUS304, in which 0Cr18Ni9 generally means national standard production, 304 generally means ASTM standard production, and SUS304 means daily standard production.
316 is a special stainless steel, due to the addition of Mo elements to corrosion resistance, and high temperature strength has greatly improved, high temperature up to 1200-1300 degrees, can be used under harsh conditions.
316Ti stainless steel coil is made by adding Ti to ordinary 316 steel to improve the intergranular corrosion resistance. Generally used in equipment resistant to corrosion by sulfuric acid, phosphoric acid and acetic acid.
304 stainless steel is a versatile stainless steel, rust-proof performance than the 200 series of stainless steel stronger. High temperature is also better, can be high to 1000-1200 degrees. 304 stainless steel has excellent stainless steel corrosion resistance and better resistance to intergranular corrosion. Of the oxidizing acid, in the experiment concluded that: concentration ≤ 65% of nitric acid below the boiling temperature, 304 stainless steel has a strong corrosion resistance. Alkali solution and most organic acids and inorganic acids also have good corrosion resistance.
304 DQ DDQ material is widely be used as all kinds of stainless steel kitchen wares, DDQ (deep drawing quality) material: refers to the material used for deep drawing (redrawing), which is what we call soft material. The main characteristic of this material is its high elongation (≧53%), hardness Low (≦170%), internal grain grade between 7.0~8.0, excellent deep drawing performance. Many companies that produce thermos and pots generally have higher processing ratios (BLANKING SIZE/product diameter), and their processing ratios are 3.0, 1.96, 2.13, and 1.98, respectively.
430 stainless steel is a general-purpose steel with good corrosion resistance. Its thermal conductivity is better than that of austenite. Its coefficient of thermal expansion is smaller than that of austenite. It is resistant to thermal fatigue and added with stabilized elemental titanium. The mechanical properties of the weld are good. 430 stainless steel for building decoration, fuel burner parts, household appliances, appliances components. 430F is added to the 430 steel easy cutting performance of steel, mainly for automatic lathes, bolts and nuts. 430LX Adds Ti or Nb to 430 steel to reduce C content and improve workability and weldability. It is mainly used in hot water tanks, hot water supply systems, sanitary wares, household durable appliances, bicycle flywheels etc.
