Carbon Steel Welding Electrode
J507DR 

Conforms to: GB/T 5117-2012 E5016-G
Equivalent to: AWS A5.5 E7015-G
Description: J507DR is a high-toughness ultra-low hydrogen sodium-type flux-coated electrode specifically for pressure vessel steel, offering excellent
          plasticity, low-temperature toughness, and crack resistance, with good process performance. It uses DC reverse polarity and allows for all-position
          welding.
Application: Used for welding high-strength low-alloy steels in pressure vessels requiring higher impact toughness, as well as for welding between
          high-strength low-alloy steels and heat-resistant or low-temperature low-alloy steels.
