Features and Applications
- Suitability for use in welding of Ni-Cr-Mo alloyed steels, fine-grained steels, cementation steels, tempered steels, cast steels etc.
- Suitability for use of applications requiring a minimum tensile strength value of 830 N/mm2
- 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
- Short arc length and staright hand movement recommended. TEMPO B 75 electrode is suitable for the first pass of multi-pass welds.
Current Type
