Hardfacing Electrodes
BOR-A(R)
AWS: SFA
EN ISO CODE:
BOR-A (R) is a hardfacing electrode operating on AC / DC(-) depositing an air hardening weld metal . The deposit displays excellent toughness and ability to withstand heavy impact loads and has excellent resistance to rolling and sliding friction. The weld deposit is machinable. Ideal for rail points and crossings, axles, wheels, gear shafts, couplings, pinion teeth, rollers, sprockets, etc.
