Description: A207 is a low-carbon Cr18Ni12Mo2 stainless steel electrode with low-hydrogen sodium coating. Use DCEP (direct current electrode positive) and can welded in all positions. Since the deposited metal contains molybdenum, it has great corrosion resistance, heat resistance and crack resistance, especially good for resisting chloride ion pitting corrosion. Application: Used for welding low-carbon 06Cr17Ni12Mo2 stainless steel structures, as well as high-chromium steels (such as Cr13, Cr17, etc.) that require no heat treatment after welding, and welding of dissimilar steels.
