Low Alloy Electrode for Low Temperature services
CLASSIFICATION : AWS/SFA-5.5: E 7015 A1
APPROVAL :
CHARACTERISTICS : A Basic coated, iron powder, Low hydrogen electrode producing 0.50% Mo weld deposit. It is welding with DC+ polarity, Electrode has high welding efficiency coupled with creep resistance properties at 525°C temperature and has excellent mechanical properties.
APPLICATION :
1) Suitable for high pressure boiler tubes and plates.
2) Fabrication for welding 0.50% Mo and 1% Cr-0.5% Mo steels used for elevated temperature services up to 525°C.
3) suitable for fine grained and creep resistant steel welding.
RE-DRY CONDITION : Re-Dry the electrode at 250°C-300°C for one hour, for best results.
