D667 Hardfacing Electrode
GB/T 984 EDZCr-C-15
Suitable for hardfacing applications requiring resistance to severe wear, corrosion, and cavitation, such as centrifugal cracking pump sleeves in the petroleum industry, mining crusher components, and valve covers in diesel engines.
A low-hydrogen sodium-type coated CCrNi cast iron hardfacing electrode. The hardfacing layer exhibits excellent wear, corrosion, and cavitation resistance below 500°C; beyond this temperature, the hardness of the hardfacing layer decreases sharply.
Direct current reverse polarity (DC+)

1. Drying requirement: Electrodes must be baked at 300～350°C for 1 hour before use and used while still warm.
2. Preheating temperature for hardfacing workpiece:
500～600°C, and remove rust, oil, oxides, etc., from the workpiece.
3. The length of each hardfacing pass should preferably not exceed 50～70mm.
4. After welding, the workpiece should be tempered at 600～700°C for 1 hour and then cooled slowly, or immediately placed in a dry and preheated sandbox or in grass ash for slow cooling.
