D&H 1423 (NS) is an ideal non synthetic electrode for welding Ni-Cr-Mo alloys as well as the clad side of joints in steel clad with a Ni-Cr-Mo alloy and for welding Ni- Cr-Mo alloys to steel and to other nickel base alloys. It is suitable for welding components in plants for chemical processes with highly corrosive media. Typical base materials which are welded with this product are ASTM B574, B575, B619, B622 and B626 with UNS No. N06022. Ideal for C-22 alloys.
1. Ensure the electrodes are dry. Re-dry the electrodes at 300-325°C for one hour.
2 Use short arc, stringer beads, and low currents.
