Properties and Applications

Basic type electrode for welding creep resistant steels. Weld metal matches the composition of steel grade 12CrMo19-5 featuring equal resistance to high-pressure hydrogen attack, creep resistance and creep rupture strength. Typical applications are : petrochemical process plants, hydrocrackers in chemical industries. Suitable to use in pressure vessels and boilers subject to operating temperatures up to 600°C. Weld metal has a low diffusible hydrogen content (4ml/100g). Preheating, interpass temperature and post weld heat treatment should be done in accordance with base metal to be welded.
