Description: A107 is a low-carbon Cr19Ni10 stainless steel electrode with low-hydrogen sodium coating. Use DCEP (direct current electrode positive) and can welded in all positions. Deposited metal has great mechanical properties and intergranular corrosion resistance. Application: Used for welding corrosion-resistant 06Cr19Ni10 stainless steel structures whose working temperature is lower than 300°C. It can also weld some steels with poor weldability (such as high-chromium steel) and surfacing stainless steel surface layers.
