SMAW
- CREEP RESISTING STEELS
CrMoV
Description
Basic coated electrode for creep resisting steels and cast steels up to 580°C
1¼Cr-1Mo-¼V electrodes used for welding high temperature steels of similar composition. These alloys provide good creep rupture properties up to about 580°C. Widely used in valve casings and steam turbines, boilers, pressure vessels and in the power generation and petrochemical industries. Its basic coating ensures excellent positional welding characteristics with good gap bridging ability. Ease of slag removal reduces post-welding cleaning operations to a minimum.
