Abstract
Exemplary alloys may comprise, by weight percentage, 13.25% to 14.75% chromium; 4.5% to 5.5% nickel; 0.11% to 0.17% carbon; 0.01% to 0.31% titanium; and the balance of weight percent comprising iron and incidental elements and impurities. Exemplary methods may include conducting additive manufacturing with an atomized alloy powder to generate a manufactured article, where the atomized alloy powder may comprise, by weight percentage, 13.25% to 14.75% chromium; 4.5% to 5.5% nickel; 0.11% to 0.17% carbon; 0.01% to 0.31% titanium; and the balance of weight percent comprising iron and incidental elements and impurities.
