312 electrodes produce a weld deposit (as welded) with the highest tensile and yield strength of any stainless arc electrode. As a result, it is one of the most widely used stainless steel electrodes for arc welding. It is used to weld dissimilar steels, abrasion resistant steels, high yield steels and for joining high temperature alloys to carbon or low alloy steels. 312 electrodes produce ductile, crack resistant, porosity-free, weld deposits with greater root penetration and better slag control in tight places. 312 is also used for Mn steels, hardening steels, armorsteels, spring steels, and as a wear resistant build-up and buffer layer for hardfacing. This electrode may be used in all positions.
