Hardfacing Electrodes
BOR- CR
AWS: SFA
EN ISO CODE:
BOR-CR is a basic coated electrode producing an air hardening weld metal which has resistance to abrasion or heavy impact or both together with machinable hardness up to 30-40HRC. The welds are machinable and are ideally suited for applications involving severe abrasion and impact. Typical applications include reclamations of equalizing beam etc.
