Introduction:

A022 is a kind of Titanium calcium type coating with ultra-low carbon Cr18Ni12Mo2 stainless steel electrode. Carbon content of deposited metal is less than or equal to 0.04%. It has excellent heat resistance, the corrosion resistance, the crack resistance and the porosity resistance. Good operation performance and high strength coating. AC/DC both can be applied.

 

Uses:

Used for welding of synthetic fiber and other equipments and the same type of stainless steel structure, In addition, it is applied to weld the steel that cannot be processed with thermal treatment, such as Chromium stainless steel, clad steel, dissimilar steel, etc.
