Suitable for welding similar types of duplex stainless steel in the offshore oil, natural gas, and petrochemical industries, such as 022Cr25Ni7Mo4N, 03Cr25Ni6Mo3Cu2N, etc.
An ultra-low carbon nitrogen-bearing duplex stainless steel electrode with a rutile-type coating. It offers excellent welding process performance, stable arc, minimal spatter, aesthetically pleasing bead formation, and resistance to coating reddening. The deposited metal has good resistance to hot cracking. Due to its extremely low carbon content and the presence of molybdenum and nitrogen, the deposited metal exhibits excellent resistance to pitting and stress corrosion cracking.
AC, DC reverse polarity (AC, DC+), with DC reverse polarity recommended.

1. Drying requirement: Electrodes must be baked at 300°C for 1 hour before use and used immediately after baking.
2. When using AC welding, spatter is greater, the coating is prone to reddening, and penetration is shallower. Therefore, DC reverse polarity welding is recommended.
3. Use as low a current as possible and short arc welding during operation, with minimal weaving amplitude.
