High Chrome Flux Cored Wire

The greater hardness of the nano-scale hardfacing alloy associated with the decreasing WC grain size reduces wear from abrasion considerably. The harder [hardmetal" counters abrasion with a greater resistance.

Wear progresses significantly slower, as the binding metal layer between the fine grain hardfacing crystallites is exceptionally thin, making it harder to wash out. Due to this structural attribute, only very small hardfacing particles are torn out of the structural bond. The spherical shape represents a further form of protection, which is further stabilized by the small grain size; small particles have to expend a great deal more energy to divide and become smaller than coarse ones.

HP Welding manufactures an extensive range of flux cored and metal cored hardfacing consumables. We offer welding wires for low, medium and high alloy hardfacing, which provide the ultimate protection against various types of wear, including abrasion, erosion, impact, mechanical fatigue, and more.

Our range of hardfacing welding wires dedicated to increasing abrasion resistance. Flux cored wires and metal cored wires suitable for increasing wear resistance of parts such as screw conveyors, fans, equipment used in agriculture & mining, grinding mills, vertical mills, screws, blades, ventilators and more.
