Weldclass Hard Facing Promax 700 3.2mm - WC-06444

700 series hardfacing welding rods for general hard-facing of ground-engaging implements and similar applications. Good abrasion resistance with moderate-to-high impact strength, typical hardness 53-56 HRC. A tough weld deposit also makes this electrode suitable for parts subject to fatigue or flexing in service. Suitable for a wide range of applications including the surfacing of post hole augers, agricultural points, shares and tynes, grader and cultivator blades, etc. Supplied in 1kg re-usable convenience pack to keep electrodes in good condition.
