Ferrotungsten is an important alloying additive in the production of hardfacing welding rods or wires. Tungsten improves the strength and toughness of the weld coating, and also improves the hardness and wear resistance of the coating. It is suitable for high-speed tool steel, alloy tool steel, heat-resistant steel, spring steel and steel products.
