• Cobalt base cored wire for gas shielded metal arc hardfacing • Co-Ci-Ni-Mo alloy deposit
• Excellent metal-to-metal wear resistance combined good corrosion resistance
APPLICATIONS
FCW 21-G is used for hardsurfacing parts subjected to a combination of impact, abrasion, compression, corrosion and high temperatures up to 900°C The toughness of the deposit allows excellent resistance to thermal cycles and shocks Less crack sensitive than other cobalt base alloys, FCW 21-G is used for building up large-scale sections
Used for integral seats and guides of large water and high-pressure valve bodies, drop forging dies, pump shafts and sleeves, hot punches etc.
