As a kind of corrosion-resistant, heat-resistant, non-magnetic metal material, stainless steel is widely used in tableware, home appliances, machinery manufacturing, building decoration and other fields.

According to the microstructure characteristics of stainless steel, it can be mainly divided into three categories: ferritic stainless steel, austenitic stainless steel and martensitic stainless steel. Among them, the use of titanium elements and high temperature corrosion resistant ferritic stainless steel, mainly used in the production of automotive exhaust pipes, hot switches, containers and other products, with good high temperature corrosion resistance. The corrosion-resistant, heat-resistant, non-magnetic austenitic stainless steel is often used in the production of household appliances, auto parts, medical devices and other products, and its excellent performance makes it widely used in various fields. In addition, magnetic martensitic stainless steel, due to its good workability and high hardness, is often used in the production of tableware, blades, mechanical parts, turbine blades and other products to meet the needs of different fields.

According to the different chemical composition, stainless steel can also be further divided into chromium manganese nickel stainless steel, chromium nickel stainless steel and chromium stainless steel. Among them, chromium manganese nickel series stainless steel has high strength, but the corrosion resistance is relatively poor, the price is relatively low, suitable for high strength, non-magnetic, wear resistance, corrosion resistance requirements of low products. Chromium nickel stainless steel has good processing properties and non-magnetic, so it is widely used in the fields of household goods, kitchen cabinets, auto parts and medical equipment.

As a multi-functional metal material, stainless steel plays an important role in different fields. Its different organizational characteristics and chemical composition classification enable stainless steel to meet the needs of different products, providing a reliable material choice for all walks of life.
