FCW 6 BC
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, to erosion and to thermal shocks
APPLICATIONS
FCW 6 BC is equivalent to FCW 6-G with a lower carbon. Easier to machine and less sensitive to cracking when compared to FCW 6-G. Used in automatic and semi-automatic welding where FCW 6-G would give cracking problems. FCW 6BC is used for hardsurfacing parts undergoing the single or combined effects of metal-to-metal wear, abrasion, temperatures ranging from RT to 800°C, impact and corrosive environments.
Examples Valve seats, valve gates, valve wedges, valve and cylinder bodies etc.
