• Cobalt base tubular wire for gas shielded metal arc hardsurfacing
• The Co-Cr-W-Ni alloy deposit benefits from stable hardness at high temperatures
• STELLOY 25-G is used for hardsurfacing parts undergoing metal-to-metal wear at temperatures up to 800°C
• The toughness of the deposit allows excellent resistance to thermal cycles and shocks
• Very resistant to creep, this alloy is used for extrusion dies, nozzles, pump shafts etc
