55FC-O is a self-shielded, flux-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.

Typical Applications
• Dredge parts
