MAC HARD E304
Description & 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 temperatures of 720 – 750°C. After machining the welds can be rehardened by oil or water quenching.
