Arcos Industries LLC offers bare wire and covered stainless steel electrodes, designed for welding stainless steels to mild steels and for welding high-strength steels that are difficult to weld with ferritic electrodes.
Both the bare wire (ER312) and covered (E312) products are suitable for welding dissimilar joints, especially if one of the base metals is a stainless high in nickel content. The weld deposit is two-phase, high in ferrite. Even with considerable dilution with austenitic forming elements, such as nickel, the microstructure is two-phase and thus resistant to weld metal cracks and fissures.
Applications include general fabrication, pipelines, pharmaceutical plants, oil and gas facilities, and marine environments. The bare wire version is available in diameters from 0.035 to 3/16 in.; the covered wires measure from 3/32 to 3/16 in.
