Abstract ATI 412 alloy is a corrosion-resistant, dual-phase, 12% Cr stainless steel that offers a good combination of strength, ductility, toughness, wear resistance, and weldability. This alloy offers potential cost savings compared to less corrosion- and wear-resistant materials based on its longer service life and the possibility of using thinner, lighter sections for a given application. This datasheet provides information on composition, hardness, and tensile properties as well as fracture toughness. It also includes information on corrosion resistance as well as forming and joining. Filing Code: SS-1130. Producer or source: Allegheny Ludlum.
