Description: AFM #12 Cobalt is similar to AFM #6 Cobalt, however AFM #12 Cobalt offers greater resistance to hot and cold abrasion at elevated temperatures. Weld deposits are harder than AFM #6 Cobalt deposits because of a higher carbide volume within its microstructure. It is excellent for abrasion and corrosion resistance, but only moderate impact. It is commonly used for cutting edges.
Typical Applications: Tipping saw blades, chipping knives, paper slitters, cutter rolls, drawing dies, turbine blades, impeller pumps, conveyor screws, valve seats, cold working tools.
