201:

Manganese-nickel stainless steel, with certain acid and alkali resistance, high density, polished without bubbles, used in watch cases, decorative pipes, industrial pipes and other shallow stretched products.

202:

It belongs to low-nickel and high-manganese stainless steel, with nickel and manganese content of about 8%. Under weak corrosion conditions, it can replace 304. It is cost-effective and is mainly used in architectural decoration, highway guardrails, municipal engineering, glass handrails, road facilities, etc.

301:

Good ductility, used for forming products, can also be hardened by work, good weldability, wear resistance and fatigue strength are better than 304 stainless steel;

302:

Corrosion resistance is the same as 304, corresponding to the domestic brand 1Cr18Ni9, because the carbon content is relatively high, so the strength is better, and it is often used in architectural decorative parts;

303:

It is a free-cutting stainless steel containing sulfur and selenium. It is used in occasions where easy cutting and high surface finish are mainly required. It is most suitable for automatic lathes, bolts and nuts;

304:

General-purpose stainless steel with good corrosion resistance, heat resistance, low-temperature strength, good mechanical properties, and high toughness. It is used in the food industry, medical industry, industry, chemical industry, and home decoration industry.

304L:

Low carbon 304 stainless steel, used in equipment parts with corrosion resistance and formability.

316:

Added Mo, excellent high temperature corrosion resistance, used in seawater equipment, chemistry, food industry, and papermaking fields.

321:

It has excellent high temperature stress breaking performance and high temperature creep resistance performance.

430:

heat fatigue resistance, thermal expansion coefficient is smaller than austenite, used in household appliances, architectural decoration.

410:

High hardness, toughness, good corrosion resistance, high thermal conductivity, small expansion coefficient, good oxidation resistance, used to manufacture parts that are corrosive to atmosphere, water vapor, water and oxidative acids

440:

High-strength cutting tool steel with slightly higher carbon content. After proper heat treatment, a higher yield strength can be obtained, and the hardness can reach 58HRC. It is among the hardest stainless steels. The most common application example is “razor blades”. There are three commonly used models: 440A, 440B, 440C, and 440F (easy to process)
