FCW WM
Metal cored tubular wire for gas shielded metal arc hardfacing
Description & applications
• Metal cored tubular wire for gas shielded metal arc hardfacing
• Medium hardness deposit offering exceptional oxidation resistance and hot toughness up to 600 C
APPLICATIONS
FCW WM is used for surfacing parts subjected to heavy compressive stresses and moderate abrasion or metal-to-metal wear, combined with mechanical and thermal shocks.
Examples
Hot and cold forging tools, hot work extrusion mandrels, drills, cutting edges on hot cutting tools…
