AWS/SFA 5.13 ECoCr-E (Coated)

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.
