Characteristics and field of use
Basic coated Stick electrode, core wire alloyed, for high quality welded seams in boiler and pipe steels, similar steel qualities, similar alloy quenched and tempered steels, untreated case hardening and nitriding steels. Preferred for 13CrMo4-5. Approved for long-term use in operating temperature ranges up to +570°C. Suitable for step cooling applications (Bruscato 15 ppm). High toughness and crack resistance, weld metal can be quenched and tempered. Very low hydrogen content (under AWS conditions HD ≤ 4 ml/100g). Deposition efficiency about 115 %. Preheating, interpass temperature and subsequent Heat Treatment according to the requirements of the base material in use (for 13CrMo4-5 at 200-250°C, temper after welding at 660-700°C, at least ½ h / furnace down to 300°C / air).
