FCW WLC O
Cored wire for self-shielded metal arc hardfacing
Description & applications
• Tubular wire for self-shielded metal arc hardfacing
• Martensitic deposit giving good resistance to metal-to-metal wear and low stress abrasive wear
• Crack free multiple layer deposits are achievable
APPLICATIONS
FCW WLC O is used for rebuilding thick layers on heavy parts subjected to high pressures and abrasion.
Examples Used for the rebuilding of blast furnace hoppers (burden area) and mill rolls moulds for light alloys, forging etc
