Abstract

A high strength, high fracture toughness steel alloy consisting essentially of, in weight percent, about C 0.2-0.33, Mn 0.20 max., Si 0.1 max., P 0.008 max., S 0.004 max., Cr 2-4, Ni 10.5-15, Mo 0.75-1.75, Co 8-17, Ce effective amount-0.030, La effective amount-0.01, Fe balance, and an article made therefrom are disclosed. A small but effective amount of calcium can be present in this alloy in substitution for some or all of the cerium and lanthanum. The alloy is an age-hardenable martensitic steel alloy which provides a unique combination of tensile strength and fracture toughness. The alloy provides excellent mechanical properties when hardened by vaccum heat treatment with inert gas cooling and has a low ductile-to-brittle transition temperature.
