The types of stainless steel include martensitic steel, ferritic steel, austenitic steel, austenitic-ferritic (duplex) stainless steel, precipitation hardening stainless steel, stainless steel plate and steel strip for pressure equipment, etc.
Martensite steel: because of its high carbon content, it has high strength, hardness and wear resistance, but its corrosion resistance is slightly poor. Ferrite steel: due to its high chromium content, it has good corrosion resistance and oxidation resistance, but its mechanical properties and technological properties are poor.
Austenitic steel: This kind of steel has good plasticity, toughness, weldability, corrosion resistance, no magnetism or weak magnetism.
