Description :

SS-2209 is designed to weld duplex stainless steels such as UNS S31803 (Alloy 2205) with excellnet pitting corrosion resistance, stress corrosion resistance and crack resistance. The weld metal can be applied for operation temperature up to 25oC and is resistant in chloride containing media against pitting corrosion media against pitting corrosion as well as crevice and stress corrosion.

Applications :

Typical application include pumps, vessels, heat exchanger, chemical equipments and pipes processing chloride containing solutions.

Note On Usage :

1. Rebake the electrodes at 200°C for 1 hour and keep it at 100°C prior to use.

2. Use stainless steel wire brush for cleaning of slags.

3. Follow the recommeded welding parameters to achieve good sound welds.
