Properties and Applications

Basic type, heavy coated electrode for welding creep resistant and high pressure hydrogen resistant steels used in construction of pressure vessels, boiler and piping subjected to operating tempetarures up to 600°C. Generally preferred in thick sections with high mechanical properties and X-ray quality necessary. Has a stable arc, low spatter and smooth weld beads. Slag removal is easy. Weld metal has 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.
