D&H 309Cb

AWS: SFA 5.4 E309Nb-16 IS: 5206 E23.12Nb R16 EN ISO CODE: 3581-A E (23 12 Nb) R 3 2

D&H 309Cb is a stainless steel electrode depositing a 25Cr - 12Ni Niobium stabilised weld metal. Ideally suited for welding stabilised and unstabilised steels to mild steels, welding the clad side of 18-8 or 18-8-Nb clad steels, overlays on ferritic steels, etc.

Precaution

1. Use short arc, stringer bead and low currents.

2. Ensure the electrodes are dry. Re-dry the electrodes at 250-300°C for one hour.
