DESCRIPTION
A Heavy-coated, Hydrogen Controlled, Iron powder Type Electrode giving 1.2 Cr/0.5 Mo weldl deposit. The Electrode gives quiet arc, negligible spatter and easily detachable slag. Welds are radiographically sound and can be used in all position. Creep and heat resistance up to 550 ̊̊C. Recommended for welding 1.2 Cr/0.5 Mo and similar Creep-Resistant steel used in Power Plants, Boilers, Oil Refineries and Chemical Plants etc.
