WB12018-G High Strength Low Alloys Steel MMA Electrodes

Fully positional, basic coated, low hydrogen electrode. Exceptional mechanical properties. Has a nominal recovery of 110%. Excellent de-slag, re-strike and general welder appeal. Used for the welding of HY80, HY100 and other high yield alloy steels where the weld metal properties must match those of the parent material after normalising followed by quenching and tempering. For the majority of materials to be welded with WB12018-G, minimum preheats between 100C and 200C with maximum interpass of 250C is required to avoid possibility of hydrogen induced “cold” cracking. Note that interpass temperatures above ~200C may yield lower strength and toughness values.
