Cobalt #21 offers excellent high temperature strength and stability. The addition of molybdenum gives it work hardening capability making Cobalt #21 excellent for hot trimming dies, extrusion dies and hot shears. This alloy has good anti-galling properties and excellent resistance to cavitation erosion and corrosion thereby making Cobalt #21 an excellent choice for fluid valve seats.

TYPICAL APPLICATIONS
Hot forming dies, hot working tools, pump shafts, high pressure-high temperature valves, valve seats, mixer blades, mill cutters, pump mill screws, gas turbines
