Stainless Steel Electrodes

D&H 310-16

AWS: SFA 5.4 E310-16 IS: 5206 E25.20R16 EN ISO CODE: 3581-A E 25 20 R 3 2

D&H 310-16 is a 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.

Precaution

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.


NOTE : A high carbon version containing 0.4C D&H 310HC is also available for welding similar composition alloys like HK40, Thermalloy 47, etc.
