Application
E312-16 electrodes were originally designed for the welding of high tensile alloys to high temperature heat-resisting alloys on turbo-jet engines. However, based upon performance, these electrodes have found wide acceptance for the welding of newly developed high yield steels and abrasion resisting steels and dissimilar steels. The weld deposit of E312-16 electrodes, “as welded,” has the highest tensile and yield strength of any stainless arc welding electrode commonly used today.
