WT 625 FC is a nickel base flux-cored alloy that can keep its strength up to 1500°F and resist corrosion against temperatures up to 1800°F. Preheat and postheat should be kept to a minimum or according to the base material. WT 625 FC produces an undiluted Fe weld deposit of 1.0% max. Typical applications include overlaying steel, joining stainless, and welding various nickel alloys. WT 625 FC is good for joining stainless due to its supplemental Mo required to prevent pitting corrosion.
