Properties And Applications

Basic type heavy coated electrode for welding creep resistant steels used in construction of pressure vessels, boiler and piping, subjected to high operating temperatures. Generally used in joining and maintenance jobs in power plants, chemical and petrochemical industries. Preheating, interpass temperature and post-weld heat treatment should be done in accordance with base metal to be welded.
