Description :

It is stabilized with columbia (Niobium) to prevent intergranular corrosion. Better corrosion. Better corrosion resistance resistance than type 308. It is used for welding type 321 and 347 stainless steels. It is provides good corrosion resistance inservice temperature up to 760 degress C.

Applications :

Typical applications include welding of corrosion resistance steels in high temperature services found in chemical refineries, smelter and power plants.

Note On Usage:

1. For GTAW process, use DC-EN, Argo Shield and Tunsten Electrode.

2. For GMAW process, Spray Transfer or Short Circuit Transfer mode can be used.

3. 98% Argon -2% O2 shielding gas is recommended in GMAW process.
