GB/T 983 E312-16 AWS A5.4 E312-16 ISO 3581-B-ES 312-16
Suitable for welding various hard-to-weld steel materials prone to cracking or porosity, hardened alloy steels, as well as high-carbon steels, tool steels, and dissimilar metals.
A rutile-coated duplex stainless steel electrode with excellent welding process performance, featuring stable arc, minimal spatter, easy slag removal, and aesthetically pleasing weld appearance. The deposited metal contains 40% to 50% ferrite, providing outstanding mechanical properties and crack resistance.
AC, DC reverse polarity (AC, DC⁺), with DC reverse polarity recommended.

Welding Positions
Reference Current
| Electrode Diameter (mm) | Φ3.2 | Φ4.0 | |
| Welding Current (A) | Flat, Horizontal | 80–120 | 100–150 |
| Vertical, Overhead | 70–110 | 90–140 | |
1. Drying requirement: Electrodes must be baked at 350°C for 1 hour before use and used immediately after baking.
2. When using AC welding, spatter is greater, the coating tends to redden, and penetration is shallower; therefore, DC reverse polarity is recommended.
3. Use low current and short arc welding as much as possible during welding, with minimal oscillation amplitude.
