Specifications:
AWS A5.13
AWS Class ECoCr-C
ASME SFA 5.13
Description:
Stellite™ 1 is an electrode that has the highest hardness of cobalt alloys. Primary hypereutetic carbides are found in the microstructure which gives the alloy higher wear resistance and reductions in impact and corrosion resistance. Due to the higher hardness there is greater likelihood for stress cracking during cooling, but can be minimized with close monitoring during preheat, interpass temps, and post heating. The alloy deposits are immune to tempering. Typical applications include drawing blocks, screw presses, pump sleeves, wear pads, etc.
