Stainless steel is the abbreviation of stainless acid-resistant steel, so what are the material classifications of stainless steel? Let me introduce it to you, I hope it can be helpful to you.
The material classification of stainless steel is as follows:
1. Chemical composition classification:
Basically, it can be divided into two major systems: chromium series stainless steel (such as ferrite series, martensite series) and chromium-nickel series stainless steel (such as austenite series, abnormal series, 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. According to the type of corrosion resistance:
It can be divided into stress corrosion resistant stainless steel, pitting corrosion resistant stainless steel, intergranular corrosion resistant stainless steel, etc.
4. According to functional characteristics:
It can be divided into free cutting stainless steel, non-magnetic stainless steel, low temperature stainless steel and high strength stainless steel.
