D&H 310-15 is a basic coated 25Cr - 20Ni type electrode for welding steels of similar composition. The weld metal has excellent resistance to oxidation and scaling up to 1200°C. The electrode is also suitable for welding of hardenable steels, clad steels, C-Mo, Cr-Mo steels where pre-heat and post weld heat treatment are not feasible.
1. Use low current, short arc length and minimum weaving.
2. Ensure the electrodes are dry. Re-dry the electrodes at 250-300°C for one hour.
