D&H 309 Mo is a stainless steel electrode yielding a weld deposit of 25Cr - 12Ni - 2.5Mo, which has good oxidation resistance up to 1050°C. Ideally suited for welding 18-11-Mo type steels to mild steel, welding the clad side of 18-11-Mo clad steels, overlays on ferritic steels, buffer layers, etc.
1. Arc should be as short as possible and welding current should not be too high.
2. Ensure the electrodes are dry. Re-dry the electrodes at 250-300°C for one hour.
NOTE : D&H 309 Mo-15 conforming to AWS E309 Mo-15 is also available.
