Selectarc B77
Designed for welding steels with high yield strength > 690 MPa in offshore, crane building, heavy transport, lifting etc.
Designed for welding steels with high yield strength > 690 MPa in offshore, crane building, heavy transport, lifting etc.
Mn, Ni, Cr and Mo alloyed basic electrode for welding low alloyed steels with yield strength > 690 MPa. Crack resistant and well suited for low-temperatures, ductility down to -60°C. Preheating, interpass temperature and post weld treatment as required for the base metal. Hydrogen content: HD < 3 ml / 100 g weld metal. CEWELD E 11018-H is packed in the best in class multi layer vacuum pack to avoid costly and time consuming redrying of the electrodes.
