BÖHLER FOX DCMS Kb Stick electrode
Classifications low-alloy creep resistant
EN ISO 3580-A: AWS A5.5:
E CrMo1 B 4 2 H5 E8018-B2H4R
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 bl can be quenched and tempered. Very low hydrogen content (under
AWS conditions HD ≤ 4 ml/100g). Deb 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).
Base materials
same alloy creep resistant steels and cast steel, case-hardening and nitriding steels with comparable
comb, heat treatable steels with comparable comb, steels resistant to caustic cracking
