J507NiCU

According with GB E5015-G
Corresponding with AWS E7015-G

Introduction: J507Ni is a kind of low-alloy steel electrode with low-hydrogen natrium type coating. DCRP (Direct Current Reversed Polarity). All-position welding. It has lower diffusible hydrogen content and excellent low temperature impact toughness.

Applications: Suitable for welding medium-carbon and low-carbon pressure vessels, such as 16MnDR, etc.
