Bohler UTP 6170 Co (Corrosion Protection) NiCrMo alloys Stick Electrodes
UTP 6170 Co is suitable for joining high-temperature and similar nickel-base alloys, heat resistant austenitic and cast alloys, such as 2.4663 (NiCr23Co12Mo), 2.4851 (NiCr23Fe), 1.4876 (X10 NiCrAlTi 32 21),1.4859 (GX10 NiCrSiNb 32 20). The weld metal is resistant to hot-cracking and is used for service temperatures up to 1100º C. Scale-resistance up to 1100º C in oxidising and carburised atmospheres, e.g. gas turbines, ethylene production plants. UTP 6170 Co can be welded in all positions except vertical-down. It has a stable arc. The seam is finely rippled and notch-free. Easy slag removal. Preheating temperature should be adjusted to the base material. Post weld heat treatments can be applied independently of the weld metal.
Features
- Offers high-temperature strength and scale-resistance up to 1100°C in both oxidising and carburising atmospheres.
- The weld deposit is highly resistant to hot cracking.
- Features a stable arc, produces a finely rippled, notch-free bead, and allows for easy slag removal.
- Suitable for all positions except vertical-down
