A172 Stainless Steel Welding Electrode
GB/T 983 E307-16 AWS A5.4 E307-16 ISO 3581-A-E(18 9 Mn Mo)R 3 2 ISO 3581-B-ES 307-16
Suitable for welding ASTM 307 steel, other dissimilar steels, and overlay welding of impact corrosion-resistant steel and transition layers, such as high manganese steel, hardened steel, etc.
A Cr18Ni8Mn4 stainless steel electrode with rutile-type coating, offering excellent welding process performance, and the weld metal has superior crack resistance.
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.
