Wisdom Brand Inconel 718Wire Used for Thermal Spray Coating
Introduction
Nickel Alloy 625 is used both for its high strength and outstanding aqueous corrosion resistance. The strength of Nickel Alloy 625 is primarily a solid solution effect from molybdenum and columbium. Nickel Alloy 625 has excellent weldability. The matching filler metals are often used for dissimilar metal joining and to weld the aqueous corrosion alloy.
It can Equivalent to: Tafa 71T, Sulzer Metco 8625
Surface Preparation
Surface should be clean, white metal, with no oxides (rust), dirt, grease, or oil on the surface to be coated. Note: It is best not to handle surfaces after cleaning. Recommended method of preparation is, to grit blast with 24 mesh aluminum oxide, rough grind, or rough machine in a lathe.
Application
l Digesters
l Corrosion Resistance
l Oxidation and Heat resistant Coatings
l Protective coatings against corrosive gases, protection against scaling of conventional low-alloy steels, build up coatings for dimensional restoration.
