EnduraMet 2205

UNS #S31803

EnduraMet 2205 stainless is a duplex stainless steel that has a microstructure consisting of austenite and ferrite phases. The duplex microstructure and the chemical composition result in an excellent combination of strength and corrosion resistance. EnduraMet 2205 has twice the annealed yield strength of typical austenitic stainless steels, like 304 and 316. In the hot rolled unannealed condition, yield strength of 75 ksi (518 MPa) or higher can be achieved for bar diameters up to 1.375 in. (34.925mm). It possesses good resistance to general corrosion in many acid environments and, has excellent resistance to chloride stress corrosion cracking, pitting and crevice corrosion.
