Basic coated, extra low hydrogen controlled low alloyed high tensile steel Electrode.
CLASSIFICATION : AWS/SFA-5.5: E 11018 M
IS-1395: E76 BM 329Fe
CHARACTERISTICS : A basic coated extra low hydrogen controlled, low alloyed high tensile steel electrode. The weld metal possesses excellent strength coupled with toughness. Electrode is of radiographic quality, gives low spatter, fine bead appearance. Slag detachability is easy.
APPLICATION :
1) welding of high tensile strength steels (800 N/mm2) such as USS-1 & WEL-TEN 80 and steels conforming to ASTM A517.
2) High strength coupled with impact resistance strength at sub-zero temperature service weld
joints.
3) Earthmoving machinery, heavy structure made of high tensile steels, penstocks.
4) Extra hydrogen control ensures resistance to hydrogen induced cracking onsite conditions.
RE-DRY CONDITION : Re-Dry the electrode at 2500°C for 1 hrs, for best results.
