Key features
- Long term use approved up to +650°C.
- The fine tuning of the weld metal chemistry allows to guarantee very low impurities. Ni+Mn restriction increases Ac1 to avoid harmful microstructure transformation during PWHT.
- The CROMOCORD 91 offers excellent operability in all position welding except vertical down.
- Stable arc with low spatter, excellent slag removal and bead shape.
- Preheat min. 200°C, Interpass max. 280°C.
- Efficiency about 120%.
