A302 Stainless Steel Welding Electrode
GB/T 983 E309-16 AWS A5.4 E309-16 ISO 3581-A-E(22 12)R 3 2 ISO 3581-B-ES 309-16
Suitable for welding 06Cr23Ni13 and similar types of stainless steel, stainless steel linings, dissimilar steels, as well as high-chromium steel, high-manganese steel, etc.
Rutile-type coated Cr23Ni13 stainless steel electrode with excellent welding process performance. The deposited metal exhibits good crack resistance and oxidation resistance.
AC, DC reverse polarity (AC, DC+). DC reverse polarity is 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.
