D608 Hardfacing Electrode
GB/T 984 EDZ-A1-08
Suitable for hardfacing parts subjected to sand abrasion and light impact in agricultural machinery, mining equipment, etc.
A CrMo-type cast iron hardfacing electrode with graphite coating. The deposited metal consists of Cr and Mo carbides in a cast iron structure, providing high hardness and wear resistance, with excellent resistance to abrasion from silt and ore.
Direct current reverse polarity (DC+)

1. Drying requirement: Electrodes must be baked at 250°C for 1 hour before use and used immediately after baking.
2. Preheating temperature for hardfacing parts: 400～500°C; if the hardfacing thickness permits, first deposit a layer with J507 electrode, then perform hot hardfacing, followed by slow cooling.
3. The hardfacing layer cannot be machined by cutting; it can only be ground.
