Arcaloy 312-16

Arcaloy 312-16 electrodes were originally designed for welding of high tensile alloys to high temperature heat-resisting alloys. Usable on AC or DC current.

Features

Arcaloy 312 electrodes were originally designed for welding of high tensile alloys to high temperature heat-resisting alloys on turbo-jet engines of that time. However, based upon performance, these electrodes have found wide acceptance for the welding of high carbon steels high yield steels and abrasion resisting steels and those steels to stainless steels. The high strength of the "all weld metal" deposit is usually reduced by dilution with a dissimilar base metal.
