High strength electrode with 2.4% Ni for improved toughness down to -80°C with weld metal recovery of approx. 120%. Applications include storage tanks, process plants, railway bridges, gantries and pipework. Vacuumed packed electrodes ideal for railway site work.
Features and Applications
Suitability for use in welding fine-grained, Ni-alloyed and carbon steels as well as cryogenic steels
High ductility and crack resistance in weld deposits
Serviceability of weld metals at temperatures down to -80°C
Weld metal recovery of approx. 120%
Convenience of welding at all positions except for vertical down position
Possibility of applying same heat treatment temperatures at pre- and post-welding as well as at transition stages as those of base metal
Weld deposits with very low contents of hydrogen
Requirement of re-drying for minimum 2 hours at the temperatures between 300°C and 350°C
Vacuumed packed electrodes
