Product description
Co-Cr-W alloy GTA (TIG) welding rod for hardfacing applications. Weld metal has got high resistance to metal-to-metal wear, corrosion and high temperatures from 500°C to 900°C. Due to weld metal toughness, it is resistant to mechanical and thermal shocks. Widely used for hardfacing of hot shearing blades, ingot tong ends, valves and valve seats, nozzles and glass dies.
