Stainless steel is divided into many types, and different types of stainless steel have different uses.

201: acid and alkali resistance, high density, polished without bubbles, used for some shallow stretched products;

202: Nickel-saving stainless steel, with good mechanical properties and corrosion resistance, used to manufacture decorative panels, hardware products, etc.;

2205: For materials that require welding, such as oil refining, paper making, chemical fertilizers, petroleum;

304: Wide range of uses, good corrosion resistance and heat resistance, no heat treatment hardening phenomenon, used for decoration, home appliances, kitchen utensils, food machinery, etc.;

304L: low-carbon stainless steel, the general state is similar to 304 in corrosion resistance, and has good intergranular corrosion resistance after welding, used in coal, chemical, petroleum and other industries;

321: Add titanium to prevent intergranular corrosion, used in building materials, chemistry, agriculture;

316: Add molybdenum, corrosion resistance, atmospheric corrosion resistance, excellent high temperature strength, used in chemical, papermaking, seawater equipment;

316L: low-carbon series, excellent intergranular corrosion resistance, used in products with special requirements for intergranular corrosion resistance;

409: Ferritic stainless steel, used in exhaust pipes and heat exchangers;

410: Martensitic stainless steel, good processing performance, used in blades, bolts, nuts, etc.
