DK-18Ni (Mod)

AWS: SFA 5.5 E8018-G
EN ISO CODE:

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.
