Stainless Steel Welding Electrode A307

GB/T E309-15

AWS A5.4 E309-15

Description: A302 is a Cr23Ni13 stainless steel electrode with low hydrogen sodium coating. Use DCEP (direct current electrode positive) and can welded in all positions. The deposited metal has good crack resistance and oxidation resistance. Application: Used for welding the same type of stainless steel, special-shaped steel, high chromium steel, high manganese steel, etc. Chemical composition of weld metal(%):
