Electrodes for Low Temperature Service

DK-18Ni(Mod) is a basic coated low hydrogen electrode for low temperature application welding. Suitable for welding of DMR grade fine-grained steel, heavy section fabrication, pressure vessels, penstock pipelines, fine grained quenched & tempered steels, etc where high stress & dynamic loading service applications are involved. The weld metal is of radiographic quality. Typical material grades suitable for welding with this electrodes are- DMR 249A, C/D grades of ASTM SA-414, Grade 55 & 60 steels of SA-516, Steels conforming to SA-814, IS: 2002, IS: 2062 and equivalent grade of steels.

1. Re-dry the electrodes at 400°C for two hours as per our standard recommended practice.
2. Re-dried electrodes shall be kept in a holding oven (maintained at 150-200°C) to avoid moisture pick up.
