Cobalt 21 Powder welds have very good strength and ductility at temperatures up to 1600°F (871°C). Its deposits are resistant to thermal shock, oxidizing, and reducing atmospheres. Deposits are a solid-solution-strengthened alloy with a relatively low weight-percent carbide phase in the microstructure. Hence, the alloy is very tough and will work harden. Cobalt 21 Powder possess excellent self-mated galling resistance, and are also very resistant to cavitation erosion. Typical product applications include guide rolls, hot extrusion and forging dies, hot shear blades, tong bits, and valve trim.
