Stainless steel material according to the matrix was classified

1, ferritic stainless steel. Chromium containing 12% ~ 30%. Its corrosion resistance, toughness and weldability with chromium content increases with the increase of chloride stress corrosion resistance is superior to other types of stainless steel. 2, austenitic stainless steel. Chromium is more than 18%, still contain about 8% of the nickel and small amounts of molybdenum, titanium, nitrogen and other elements. Good comprehensive performance, corrosion resistant to a variety of media. 3, austenitic - Ferrite duplex stainless steel. The advantages of both austenitic and ferritic stainless steel, and has the superplasticity. 4, martensite stainless steel. High strength, but the plasticity and poor weldability. The characteristics of the previous: stamping processing is introduced
