FCW CV
Tubular wire for self shielded metal arc hardfacing
Description & applications
• Tubular wire for self shielded metal arc hardfacing
• Low cost version of the FCW CNV giving almost comparable results
• High chromium cast iron for hardsurfacing components subject to extremely severe abrasive wear and moderate impact up to 600°C
APPLICATIONS
FCW CV is designed to give a weld deposit of particularly high hardness and wear resistance on account of the dispersion of complex carbides it contains. This gives superior performance compared to standard chromium cast irons. Relief checking is normal.
Examples
Used for crushing, riddling, blast furnace hoppers and throats, ovens etc.
