Check the listing for details. 55FC-O .035 MIG Hardfacing 1 lb Spool Welding Wire Blue Demon. Condition: New. Listed at 29.64 USD. 55FC-O is a self-shielded, metal-core wire that deposits a premium martensitic alloy steel of H-12 tool steel composition. It has excellent resistance to adhesive (metal-tometal) wear. It also has good resistance to abrasion and impact, and maintains its hardness up to 1000°F. It is designed for use as an overlay on carbon and low alloy steels. Because of its high hardenability, proper preheat may be required for crack-free deposits, particularly on low alloy steels. 55FC-O is formulated to optimize performance on small 110/220V type wire welding machines.
