ABSTRACT:
A high strength, low alloy, low to medium carbon steel casting is provided of the Fe/Cr/C type containing by weight about 0.1 to 0.5% Si, said steel characterized by the presence of a small but effective amount of each of Cu and Ni sufficient to enhance the mechanical stability of retained austenite formed following quenching of said steel from its austenitizing temperature, the amount of Ni being at least sufficient to counteract the destabilizing effect of Si on austenite. Preferably the steel also includes small but effective amounts of Al, Ti and Nb sufficient to provide a fine grained microstructure.
