FCW 12
Cobalt base tubular wire for gas shielded metal arc hardsurfacing
Description & applications
• Cobalt base tubular wire for gas shielded metal arc hardsurfacing
• Exceptional resistance to metal-to-metal wear in corrosive media at high temperatures, to erosion and to thermal shocks
APPLICATIONS
FCW 12 is used for hardsurfacing parts undergoing the single or combined effects of metal-to-metal wear, abrasion, temperatures ranging from RT to 800°C and corrosive environments.
Examples
Saw teeth, cams, shafts, tappets and push rods for engines, screw conveyors and augers for rubber and plastics, seats and valves for oil and gas…
