What are the material classifications of stainless steel?

Stainless steel is the abbreviation of stainless steel and acid resistant steel, so what are the material classifications of stainless steel? Let me introduce it to you, hoping it can be helpful to everyone.

The material classification of stainless steel is as follows:

1. Chemical composition classification:

Basically, it can be divided into two major systems: chromium based stainless steel (such as ferrite series and martensite series) and chromium nickel based stainless steel (such as austenite series, abnormal series, and precipitation hardening series).

2. Metallographic organization classification:

It can be divided into austenitic stainless steel, ferritic stainless steel, martensitic stainless steel, duplex stainless steel, and precipitation hardening stainless steel.

3. Classified by corrosion-resistant type:

It can be divided into stress corrosion resistant stainless steel, pitting corrosion resistant stainless steel, intergranular corrosion resistant stainless steel, etc.

4. Classified by functional characteristics:

It can be divided into easy cutting stainless steel, non magnetic stainless steel, low-temperature stainless steel, and high-strength stainless steel.
