J507Mo

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


Introduction: J507Mo is a kind of H2S corrosion-resistant low-alloy steel electrode with low-hydrogen natrium type coating. DCRP (Direct Current Reversed Polarity). All-position welding. The weld metal has excellent corrosion-resistance, crack-resistance and welding performance.


Uses: Suitable for corrosion-resistant steel containing Mo, V or low Al, etc., such as 12CrMoVAl and 400℃ S and H2S corrosion-resistant steel.

Instructions:
1.The electrodes must be baked under about 350℃ for an hour before welding, and used as soon as baking is completed.
2.The stains on the weldments, such as rust, oil stains, moisture, etc., must be cleared away before welding.
3.When welding, short arc must be used and stringer bead is suitable.
