Features and Applications
- Basic type Mn-Mo-Ni alloyed, thick coated electrode.
- High ductility and high resistance to cracking obtained in welding high-strength, quenched and tempered, fine-grained structural steels
- Suitability for use in welding of materials with service temperatures between -60°C and + 400°C.
- Very high values of impact resistance after aging
- Convenience of welding at all positions except for the vertical down position.
- Possibility of applying same heat treatment temperatures at pre- and post-welding as well as at transition stagesas those of base metal
- Weld deposits with very low contents of hydrogen
- Welding of the all-weld metal test assembly shall be executed in the temperature range 120 °C to 175 °C with the exception of the first layer which may be welded without preheat.
- Re-drying: 300-350°C / min. 2h
Current Type
- DC(+)
