Stainless steel bars are made from stainless steel ingots by hot rolling or forging. They have good corrosion resistance, high strength and resistance to high temperature, high pressure, radiation and low temperature. Stainless steel bars are increasingly being used in a wide range of applications, such as foundations for high-rise buildings in cold regions, barrier nets along highways, and household necessities.

Type 201 stainless steel is a low-cost alternative to traditional chromium-nickel stainless steels such as 301 and 304, where the nickel is replaced by added manganese and nitrogen.Type 201 is essentially non-magnetic in the annealed condition, but becomes magnetic after cold working and can achieve high tensile strengths.Type 201 can be used as a replacement for Type 301 in many applications. It is used primarily for decorative piping, industrial piping, and some shallow drawn products.

301 is the steel grade most easily strengthened by cold deformation. Cold distortion processing increases the strength and hardness of the steel and retains sufficient plasticity and toughness. In addition, this steel has good rust resistance under atmospheric conditions, but it is highly corrosive. It is mainly used in automobile industry, electronic and electrical appliances, hardware products, building decoration and so on.

304 stainless steel is a general-purpose stainless steel material with better rust resistance than 200 series stainless steel materials. High temperature resistance is also better, up to 1000-1200 degrees.304 stainless steel has excellent corrosion resistance and good intergranular corrosion resistance, high strength and toughness, smooth and beautiful surface, easy to process. It is mainly used in building decoration, kitchenware and tableware, food processing equipment, medical equipment, chemical equipment, automobile parts and so on.

Compared with 304 stainless steel, 316 stainless steel has a molybdenum content of 2-3%, which makes it more resistant to corrosion by acids, alkalis, salts and other chemicals, and is especially resistant to chlorides, which makes it suitable for a variety of harsh corrosive environments. It is usually used in pulp and paper equipment, heat exchangers, dyeing equipment, film processing equipment, pipelines, building exterior materials in coastal areas, and bracelets and cases of high-grade watches.

405 Stainless steel belongs to ferritic stainless steel, with certain magnetic properties, and a remarkable feature is its ductility, so that the metal will not crack or break when doing bending and rolling and other molding processes. It is mainly used in building decoration, automobile industry, home appliance industry, food processing industry, chemical equipment and so on.
