Key features
- Very clean welding wire with guaranteed X<15 ppm Bruscato factor, and with controlled As, Sb, Sn content against temper embrittlement.
- Ideal for the welding of creep resistant steels
- Also suitable for the welding of 1¼Cr 1Mo steels where improved resistance to hydrogen attack or corrosion by sulphur is required. Main applications are welding of boilers, plates and tubes as well as oil refineries e.g. in crack plants produced from mainly 10CrMo9-10 (ASTM A335 Gr. P/T22).
