In this paper, a high-chromium stainless steel alloy having improved resistance to stress corrosion cracking in high temperature water is comprised of, in weight percent; about 22 to 32 percent chromium, about 16 to 40 percent nickel, up to about 10 percent manganese, and the balance substantially iron.Abstract:
A high-chromium stainless steel alloy having improved resistance to stress corrosion cracking in high temperature water is comprised of, in weight percent; about 22 to 32 percent chromium, about 16 to 40 percent nickel, up to about 10 percent manganese, up to about 0.06 percent carbon, and the balance substantially iron. A preferred high-chromium alloy is further comprised of about 2 to 9 weight percent of a metal from the group consisting of titanium, niobium, tantalum, and mixtures thereof. Another preferred high-chromium alloy is further comprised of a platinum group metal in an effective amount to reduce the corrosion potential of the alloy in high-temperature water provided with hydrogen.read more
