ISC S22253Ferrite - Austenite duplex stainless steel
ISC S22253 equal material :ISC S22253, S31803 ,1.4462, 022Cr22Ni5Mo3N
ISC S22253duplex stainless steel is a kind of ferrite to austenite stainless steel, belong to the second generation of duplex stainless steel in the alloy.In the early 1980 s, our country began to develop and ISC S22253 duplex stainless steel is 00 cr22ni5mo3n duplex stainless steel,of ferrite and austenite F A each account for about 50%. It combines ferrite and austenite is the most useful performance: ferrite phase steel has strength and resistance to chloride stress corrosion performance, austenitic phase steel has good toughness and corrosion resistance. ISC S22253, therefore,has the very good resistance to chloride stress corrosion cracking, are better than ferritic stainless steel chloride pitting and crevice corrosion resistance, good common corrosion resistance, good resistance to sulfide stress corrosion capability. S31803 duplex stainless steel, as a kind of good corrosion resistance, high strength, yield strength of austenitic steel for other 2-3 times), including the steel chromium and molybdenum content is very high, so has excellent corrosion resistance and uniform corrosion. Duplex microstructure ensures that the steel has the ability of high resistance to stress corrosion cracking, and high mechanical strength at the same time.
