Hard Facing Electrode
Hard Cover 460 (HC460) is an economical, general hard facing electrode where some impact is combined with abrasion. In the as-deposited condition, the micro structure consists of martensite and some carbides. This is a great hard facing electrode for low open circuit voltage AC welding machines.
Typical Applications :
Surfacing and build-up of worn and new machine parts of cast steel, steel and man-ganese steel, used for earth borders, cater-pillar drives, stampers, shovel teeth, pressure rollers, conveyors, hammer mill parts, crusher jaws, and dredger teeth.
