Hardfacing Welding Electrodes
Hardfacing Electrode/ Hardfacing Rod/ Hardfacing Wire
Introduction:
The D608 is a cast iron hardfacing welding electrode that is suitable for AC/DC and DCRP (direct current reversed polarity) welding. The surfacing metal is Cr and Mo carbide with a cast iron structure for high hardness and wear resistance.
Applications:
Used for welding machinery parts with high impact requirements such as agricultural machinery, mining equipment, etc.
Chemical Composition of Deposited Metal (%):
| Chemical Composition | C | Mo | Cr |
| Guarantee Value | 2.50~4.50 | 3.00~5.00 | 3.00~5.00 |
Hardness of Surfacing Layer:
HRC≥55
Reference Current (AC, DC ):
| Electrode Diameter(mm) | φ3.2 | φ4.0 | φ5.0 |
| Welding Current (A) | 90~120 | 130~160 | 170~210 |
Instructions:
1. The electrodes must be baked under about 250℃ for an hour before welding.
2. In surfacing welding, the weld should be preheated to 400-500℃. If the surfacing thickness permits, a surfacing layer can be made with J507 at first. Then the surfacing welding should be done when there is enough heat. The weld should be cooled down slowly after welding.
Packing Details:
In cartons of 20kgs/net, consisting of 8 boxes x 2.5kgs for 2.5mm, & 4 boxes x 5kgs for other sizes.
