A212 Stainless Steel Welding Electrode
GB/T 983 E318-16 AWS A5.4 E318-16 ISO 3581-A-E(19 12 3 Nb)R 3 2 ISO 3581-B-ES 318-16
Suitable for welding stainless steels such as 06Cr17Ni12Mo2Ti and 06Cr17Ni12Mo2Nb, including components exposed to highly corrosive media like urea synthesis towers and vinylon equipment.
A Cr18Ni12Mo2Nb stainless steel electrode with rutile-type coating, offering excellent welding process performance and resistance to intergranular corrosion.
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 higher, the coating tends to redden, and penetration is shallower; therefore, DC reverse polarity welding is recommended.
3. Use low current and short arc welding as much as possible during welding, with minimal oscillation amplitude.
