2205

UNS #S31803

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