Hardfacing Electrodes
SMA
AWS: SFA
EN ISO CODE:
SMA is a basic coated electrode operating on AC/DC(+) producing a tough austenitic manganese steel weld metal. The deposit work hardens in service and has excellent resistance to wear by impact. Typical applications include surfacing of parts subjected to abrasion and heavy impact as in the case of crusher jaws, bucket teeth and lips, rail crossing, etc.
