AKD717
HRC:≥60
Standard:
GB/T984 EDD-B-15
Description: The AKD717 tungsten carbide surfacing electrode is made of HO8A steel strip, rolled into an “O” shape, and the cast tungsten carbide with a content of more than 60% of the weight of the welding core is used as the welding core. Tungsten carbide transition C and W. The arc is stable, DC welding is suitable, and a small current is used.
Application: Suitable for surfacing mechanical parts that are resistant to strong rock wear, such as the claw back of the three-cone drill bit, blower blades, powerful coal mining drums, sugar press rolls, concrete mixer blades, etc.
Typical Chemical Composition(%):
C:1.5-4.0 Si:4.0 Cr: 3.0 Mo: 7.0 Mn: 3.0 Ni: 3.0 W: 50.0-70.0
Recommended welding parameters:
3.2mm: 350mm 120-160A
4.0mm: 350mm 140-190A
Notes on usage:
1. The electrode must be baked at 360C for 1 hour before welding.
2. The workpiece must be preheated to above 300C before welding to avoid cracking.
