AWS/SFA 5.13 RCoCr-B (Bare)
AWS/SFA 5.13 ECoCr-B (Coated)
Cobalt #12 is similar to Cobalt #6, however Cobalt #12 offers greater resistance to hot and cold abrasion at elevated temperatures. Weld deposits are harder than Cobalt #6 deposits because of a higher carbide volume within its microstructure. Cobalt #12 is excellent for abrasion and corrosion resistance, but only moderate impact. This alloy is commonly used for cutting edges.
Tipping saw blades, chipping knives, paper slitters, cutter rolls, drawing dies, turbine blades, impeller pumps, conveyor screws, valve seats, cold working tools.
