INCONEL 625

Introduction:

Inconel 625 is used both for its high strength and outstanding aqueous corrosion resistance .  The strength of inconel 625 is primarily a solid solution effect from molybdenum and columbium. Inconel 625  has excellent weldability. The matching filler metals are often used for dissimilar metal joining and to weld the aqueous corrosion alloy.

Equivalent to :  MEC 860, Tafa 71T,  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 aluminium oxide.  Rough grind or rough machine in a lathe.

Application

a)Digesters
b)Corrosion Resistance                       
c)Oxidation and heat resistant coatings.     
d)Protective coatings against corrosive gases, protection against scaling of conventional low-alloy  steels, build up coatings for dimensional restoration
