J507FeNi

According with GB E5018-G
Corresponding with AWS  E7018-G


Introduction: J507FeNi is a kind of low-alloy steel electrode with iron powder low-hydrogen type coating. DCRP (Direct Current Reversed Polarity). All-position welding. It has lower diffusible hydrogen content and excellent low temperature impact toughness.


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