D&H 2209(NS)

AWS: SFA 5.4 E2209-16 EN ISO CODE: 3581-A E 22 9 3 N L R 3 2

D&H 2209(NS) is a non-synthetic electrode depositing duplex stainless steel weld metal. It is ideal for welding duplex stainless steels. The weld metal possesses excellent corrosion resistance in marine & paper environments. Suitable for welding duplex stainless steels having Cr < 25% and other grades like UNS 32205, UNS 31803, etc.

Precaution

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

2. Use stringer beads, short arc and smallest possible size, which helps in reducing the heat input.


Note : D&H 2209-15 (NS) conforming to AWS E2209-15 is also available.
