A202 stainless steel electrodes meet the GB E316-16 rather AWS E316-16 
 Description: A202 is a titanium calcium type Cr18Ni12Mo2 low-carbon stainless steel electrode. As the weld metal to add Mo, it has good corrosion resistance, heat resistance and crack resistance, particularly pitting good against chloride ion. AC-DC dual-use, excellent performance of the operating process. 
 Uses: Used for welding in the organic and inorganic acids (non-oxidizing acid) media work 0Cr18Ni12Mo2 stainless steel or welding for dissimilar metals.
