Classifications low-alloy creep resistant
EN ISO 3580-A: AWS A5.5:
E Mo B 4 2 H5 E7018-A1H4R
Characteristics and field of use
Basic coated Stick electrode for high quality welded joints0n creep resistant boiler and pipe steels,
preferred for 16Mo3. Approved for long-term use in operating temperature ranges up to 550°C. Particularly
high toughness and crack resistance. Very low hydrogen content (under AWS conditions
HD ≤ 4 ml/100g). Deposition efficiency about 115%.
