201: Manganese instead of nickel stainless steel, with certain acid and alkali resistance, high density, polished without bubbles, used in cases, decorative tubes, industrial tubes and some other shallow drawing products.
202: a low nickel high manganese stainless steel, nickel and manganese content of about 8%, weak corrosion conditions, can replace 304, cost-effective, mainly used in architectural decoration, highway guardrails, municipal engineering, glass handrails, highway facilities, etc.
304: general purpose stainless steel, good corrosion resistance, heat resistance, low temperature strength and mechanical properties, high toughness, used in the food industry, medical industry, industry, chemical industry, home decoration industry.
304L: Low carbon 304 stainless steel, used for corrosion resistance and formability of equipment and machine parts.
316: with added Mo, excellent high temperature corrosion resistance, used in seawater equipment, chemical, food industry, paper industry.
321: Excellent high temperature stress breaking properties and high temperature resistance to subduction.
430: heat-resistant fatigue, coefficient of thermal expansion is smaller than austenite, used in household appliances, architectural decoration.
410: high hardness, toughness, good corrosion resistance, large thermal conductivity, small expansion coefficient, good oxidation resistance, used in the manufacture of atmospheric, water vapour, water and oxidizing acid corrosive parts.
