Cobalt 21 Electrode: This alloy has excellent strength and ductility at temperatures up to 1600°F (871°C). Its deposits are resistant to thermal shock, oxidizing, and reducing atmospheres. It is a solid-solution-strengthened alloy with a relatively low weight-percent carbide phase in the microstructure. Deposits possess excellent self-mated galling resistance and also are very resistant to cavitation erosion. This product’s typical applications include guide rolls, hot extrusion and forging dies, hot shear blades, tong bits, and valve trim.
