CLASSIFICATION : AWS/SFA-5.5: E 9018 G
IS-1395: E 63 BG 129Fe
IS-1395: E 63 BG 129Fe
CHARACTERISTICS :
Basic type ,iron powder, hydrogen controlled medium heavy coated electrode producing 1.5 Cr 1.0% Mo and 0.2 V weld deposit. Electrode has high welding efficiency coupled with creep resistance properties at high temperature and has excellent mechanical properties.
APPLICATION :
- Suitable for high pressure boiler tubes and plates.
- Fabrication for welding Cr-Mo-V steels used for elevated temperature services up to 600°C.
- suitable for fine grained and creep resistant steel welding.
- Suitable for steel , thermal and chemical plants.
RE-DRY CONDITION : Re-Dry the electrode at 250°C-300°C for one hour, for best results.
