Instructions:
A022 is an ultra-low carbon Cr18Ni12Mo2 stainless steel electrode with a titanium calcium coating. Its deposited metal has a carbon content of 0.04, and it has good heat resistance, corrosion resistance, crack resistance, and porosity resistance. It also has good operational performance, red resistance, and good strength. Can be used for both AC and DC.
Purpose:
Used for welding equipment such as synthetic fibers and similar types of stainless steel structures, it can also be used for chromium stainless steel, composite steel, dissimilar steel, etc. that cannot be heat-treated after welding.
