FCW 1
Hardfacing Cobalt base
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, where shocks are low to moderate
APPLICATIONS
FCW 1 is used for hardsurfacing parts undergoing the single or combined effects of heavy metal-to-metal wear or abrasion, temperatures ranging from RT to 800°C and corrosive environments.
Examples Steam valves, wire guides, rubber and plastic mixers, extrusion screws, conveyors…
