Application\/properties:<\/strong><\/p>\n\n\n\n

Basic electrode that uses nano technology in a humid environment with 80% humidity, the electrode coating is resistant to moisture absorption for 9 hours. This electrode is suitable 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 +570\u00b0C. Welds are of X-ray quality.Preheating, interpass temperature and post-weld heat treatment in accordance with base metal to be welded.<\/p>\n\n\n\n
