Alloy 625 FC is a nickel-chromium-molybdenum-iron flux cored filler used for nickel base alloys which contains chromium-molybdenum or iron-chromium and themselves to steel.
Inconel® 625 & 825, alloy 25-6 Mo and overlaying steel as well as joining stainless may bean excellent choice also. This weld metal has good strengths and resists corrosion and oxidation up to 1500 °F. Some of these base metals are found with specifications of ASTM B443, B444, B446 (all listed under UNS 06625), B407, B409, B512, B564 (all listed under UNSN08800)
