Stainless steel is divided into martensitic stainless steel, ferritic stainless steel, duplex stainless steel, austenitic stainless steel, and precipitation hardening stainless steel.
1. Martensitic stainless steel: stainless steel whose mechanical properties can be adjusted by heat treatment is a kind of hardenable stainless steel. The typical grade is Cr13 type. Mainly used
for steam turbine blades, tableware, surgical instruments.
2. Ferritic stainless steel: The chromium content is 15%~30%, and it has a body-centered cubic crystal structure. This type of steel generally does not contain nickel, and has the characteristics of
high thermal conductivity, small expansion coefficient, good oxidation resistance, and excellent stress corrosion resistance.
3. Duplex stainless steel: refers to the stainless steel with ferrite and austenite each accounting for about 50%, and generally less content needs to be at least 30%.
4. Austenitic stainless steel: Austenitic stainless steel refers to stainless steel with austenitic structure at room temperature. Austenitic stainless steel is non-magnetic and has high toughness
and plasticity, but its strength is low, it is impossible to strengthen it through phase transformation, and it can only be strengthened through cold working.
5. Precipitation hardening stainless steel: refers to the addition of different types and quantities of strengthening elements on the basis of the chemical composition of stainless steel, and
through the precipitation hardening process, different types and quantities of carbides, nitrides, carbonitrides and intermetallic compounds are precipitated. A class of high-strength stainless
steel that
maintains sufficient toughness in strength, referred to as PH steel.

Steel is an alloy of iron and carbon. Stainless steels are steels containing at least 10.5% chromium, less than 1.2% carbon and other alloying elements. Stainless steel’s corrosion resistance and
mechanical properties can be further enhanced by adding other elements, such as nickel, molybdenum, titanium, niobium, manganese, etc.
