Postalloy® 306HD Electrode

Postalloy® 306HD, for welding construction grades of carbon and low allow steels, offers excellent weldability on either AC or DC Electrode Positive, in any position. Weld deposits are dense, porosity-free and “X-Ray” quality. The low hydrogen moisture resistant coating helps to prevent underbead cracking and delayed brittle fracture. Furthermore, the coating is non-conductive, to eliminate side-arcing.
