Prime-Arc 300 HNW (hard-facing, non-check cracking wire) and HNE (hard-facing, non-check cracking electrode) welding consumables are economical, general purpose, hard-facing alloys that offer a good balance of impact and abrasion resistance.
Prime-Arc 300 is designed for use in both metal-to-metal and metal-to-earth applications. It can be applied to carbon, low-carbon, low-alloy, and manganese steels. Applications include metal-to-metal wear, large build-ups, no chromium carbide plates, tough magnetic weld deposit, good for tungsten carbide, drop hammers, conveyors, pulverizers, dredging elements, bucket teeth, trampers, and boring tools.
