Application / Properties: Electrode for welding of creep resistant and high-pressure hydrogen resistant steels used in the construction of pressure vessels, boilers and piping subjected to operating temperatures up to+570C.Owing to its double covering (up to 3.25mmǾ), the electrode shows a stable and concentrate arc, thus being well suited for root pass and positional welding . weld are of X-ray quality.

Preheating, interrpass temperature and post-weld heat treatment in accordance with base metal to be welded.
