Properties and Applications

Basic type, heavy coated electrode for welding creep resistant steels employed in the fabrication of pressure vessels, boilers and pipes, subjected to operating temperatures of up to 570°C. Welds are of X-ray quality. Weld metal has a low diffusible hydrogen content (4ml/100g). Generally preferred in thick sections an where high mechanical properties and X-ray quality are necessary. Preheating interpass temperature and post-weld heat treatment shall be done according to base metal used.
