    Tungsten Carbide Hardfacing from Hardface Technologies

    Mig Tungsten Carbide is a welding process that deposits extremely hard tungsten carbide particles (70 Rc) in the weld puddle of a hardfacing wire as it is applied. Mig Carbide is unsurpassed in abrasion and impact resistance when applied with POSTALLOY PS98. This is because softer wires wear away allowing the tungsten carbide to literally fall
