Mac Hard E304
57-59 RC
Descriptions & Applications:
The electrode is designed to deposit wear resistant overlays on all ferrous metals where high resistance to impact and abrasion is required. The electrode is all positional with a metal recovery rate of 110%. The welds are non-machinable in the as welded state but can be softened by heat treatment at 720 - 750°C. After machining the welds can be rehardened by oil or water quenching. Applications include earth moving equipment, scraper blades, bucket lips and facings, farm implements and any application subject to impact and abrasion.
