Duplex 2205 2507 254SMO 253Ma Stainless Steel Strip
Product Description
Duplex stainless steel has the austenite + ferrite dual phase structure, and the content of the two phase structures is basically the same, so it has the characteristics of austenitic stainless steel and ferritic stainless steel. The yield strength can reach 400Mpa ~ 550MPa, which is twice that of ordinary austenitic stainless steel. Compared with ferritic stainless steels, duplex stainless steels have high toughness, low brittle transition temperature, and significantly improved intergranular corrosion resistance and welding performance; while retaining some of the characteristics of ferritic stainless steels, such as 475℃ brittleness, heat High conductivity, small linear expansion coefficient, superplasticity and magnetic properties. Compared with austenitic stainless steels, duplex stainless steels have high strength, especially yield strength is significantly improved, and pitting corrosion resistance, stress corrosion resistance, corrosion fatigue resistance and other properties have also been significantly improved.
