FCW VN O
Tubular wire for self-shielded metal arc hardfacing
Description & applications
• Tubular wire for self-shielded metal arc hardfacing
• Chromium carbide type matrix with vanadium carbide particles dispersed uniformly throughout the deposit thickness
• For improving abrasion resistance: ideal complement to conventional chromium carbide deposits at the deposits at the final pass or for local reinforcement.
APPLICATIONS
FCW VN O is used for hardfacing components undergoing heavy wear by earth, sand or other abrasives. Relief checking is normal.
Examples
Used for mixer blades, extruder screws, crusher component armouring, tile and brick making equipment etc.
