ABSTRACT:
Austenitic stainless steel casting alloys which have excellent resistance to seawater, other chloride solutions, and a broad spectrum of other chemical substances, but which do not require solution heat treatments, after welding or other exposure to heat, such as in the slow cooling of large, rangy castings from the molten state. The alloys also posses very high tensile elongation values, excellent weldability and resistance to thermal and mechanical shock. The alloys are comprised, by weight, of from about 28% to about 34% Ni, from about 22% to about 26% Cr, from about 3.3% to about 4.4% Mo, from about 2% to about 3% W, from about 1% to about 3% Cu, from about 0.2% to about 0.9% Si, from about 0.3% to about 1.3% Mn, up to about 0.05%, but preferably not more than about 0.03% C, and the balance essentially iron, plus the usual impurities encountered in conventional production practice. The alloys may optionally contain up to about 0.3% Nb, up to about 0.20% Ti, and up to about 0.25% each of Al and V.
