Hydrogen controlled, Basic coated , Iron powder type electrode for outstanding toughness Impact properties.

CLASSIFICATION : AWS/SFA-5.1: E 7018-1, BS 639 E 5122RR21032
IS-814: EB 5426 H3JX, DIN 1913 E 5122RR1135200
APPROVAL : BV, BAX, PDIL
CHARACTERISTICS :

An iron powder, hydrogen controlled electrode producing tough & ductile weld metal for welding heavy & rigid structure subjected to dynamic loading. The weld metal is of radiographic quality and displays remarkable mechanical properties like toughness resistance even at -50°C temperature.

APPLICATION :
  • Suitable for high pressure boilers vessels.
  • Carbon steel rigid and heavy structures.
  • Steels sensitive to hydrogen embrittlement and pron to crack.
  • Industrial equipment subjected to severe impact.
  • off-shore drilling rigs and flat forms
  • Equipments require heavy impact at minus 46°C.
  • Thick plate of carbon steels.
RE-DRY CONDITION : Re-Dry the electrode at 250°C-300°C for one hour before use.
