D256 Hardfacing Electrode
GB/T 984 EDMn-A-16
Suitable for hardfacing impact-prone and wear-prone parts such as various crushers, high manganese steel rails, buckets, bulldozers, etc.
A high manganese hardfacing electrode with low-hydrogen potassium-type coating. The deposited metal is austenitic high manganese steel, featuring work hardening, toughness, and wear resistance.
AC, DC reverse polarity (AC, DC+)

1. Drying requirement: Electrodes must be baked at 300～350℃ for 1 hour before use and used while warm.
2. Use low current and narrow beads during hardfacing.
3. When hardfacing high manganese steel workpieces, remove the fatigued layer or perform water toughening treatment, or use a chromium-manganese steel electrode (e.g., D277) for backing.
4. Significant yellow smoke is generated during hardfacing; ensure adequate ventilation and operate from upwind positions.
