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.

With a titanium content of not less than 5 times the carbon content, Type 321 stainless steel offers oxidation resistance at 816°C (1500 °F) and higher creep and stress fracture properties than 304 and 304L alloys. It also has good low-temperature toughness. It is primarily used in aerospace, petrochemical, power, automotive exhaust, and food processing equipment.

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.

Stainless steel coil is widely used in the production of equipment and components that require good overall performance (corrosion resistance and formability), such as food production equipment, tableware, chemical equipment, nuclear energy, exterior materials, construction materials, automotive components (semi-liquid tanks and troughs), medical equipment, the fiber industry, and ship components.

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.
