Mac Hard E301
37-40 RC
Descriptions & Applications:
Hard facing electrode designed for applications where high resistance to impact is the main requirement. The electrode is all positional and has a metal recovery rate of 120%. Welds can be softened by heat treatment at 720-750°C, machined and subsequently re-hardened by oil or water quenching. Used for the hard facing of crusher jaws, dredger tumbler plates, punches, shears, guillotine blades, tractor idler wheels, roller and track links. Also suitable for depositing buffer layers and for building up multi-layer deposits on badly worn components.
