EnduraMet 2304 is a lean duplex stainless steel with a microstructure consisting of austenite and ferrite phases. This duplex microstructure and the chemical composition result in an excellent combination of strength and corrosion resistance. EnduraMet 2304 stainless has twice the annealed yield strength of typical austenitic stainless steels, like 304. 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. (34.925 mm). It possesses good resistance to general corrosion in many acid environments, chloride stress corrosion cracking, pitting and crevice corrosion.
