Characteristics and field of use
Basic coated stick electrodes, core wire alloyed, for components subject to high temperature stress in boiler, appartatus and pipeline construction, as well as in the petrochemical industry e.g. in cracking plants. Preferred for 10CrMo9 10. Approved for long-term use at operating temperatures of up to 600°C. For step cooling applications, a product range, specially developed for the purpose, is available. Crack-resistant, tough weld metal, high creep strength. Good welding properties in all positions other than vertical down. Weld metal can be nitrided, quenched and tempered. Deposition efficiency approx. 115%, low hydrogen content (under AWS conditions HD ≤ 4 ml/100 g).
