Executive Cobalt 12 is a cobalt based alloy designed for abrasion and corrosion resistance at elevated temperatures with a medium-high hardness. The weld deposits display chrome carbides for abrasion resistance, tungsten for high temperature strength, and the high chromium level provides corrosion and oxidation resistance. Executive Cobalt 12 retains its hardness to high temperatures and is less likely to crack than Executive Cobalt 1. While the cobalt-chromium deposits soften somewhat at elevated temperatures, they normally are considered immune to tempering. The welded deposits have a low coefficient of friction and will develop a high polish in service.
