Abstract:
A steel component material composed of steel selected from a group consisting of AISI 4130, AISI 8630 MOD3 and ASTM-A182 F6NM steels having a defined range of tensile strength, yield strength and hardness and having improved strength and wear resistance achieved by adhering to a heat affected zone of the steel component by welding, plasma spraying or dip coating a cladding of high strength precipitation hardenable or age hardenable Inconel (RTM) 725 metal alloy material of higher tensile strength, yield strength and hardness as compared with said defined range of tensile strength, yield strength and hardness, the Inconel (RTM) 725 metal alloy of the metal clad steel component being subjected to post-deposition heat treatment to soften the heat affected zone of the steel component and simultaneously harden the cladding of precipitation hardenable or age hardenable Inconel (RTM) 725 metal alloy material on the heat affected zone.
