MSD-50A hard surface wear-resistant electrode
Description: The electrode is a low hydrogen sodium type coating surfacing electrode, can be AC, DC dual-use, welding arc stability, small spatter, easy slag off, forming a smooth, fast deposition speed, single or multi-layer surfacing There is no shedding phenomenon, the weld metal has high toughness and good wear resistance.
Uses: Suitable for all types of crushers. Pulverizers, hammerheads, jaws, buckets, bulldozer blades and other parts of the wear surface welding. Surfacing layer hardness: HRC>50

Precautions:
1. If the electrode gets wet, it should be baked at 300-350°C for 1 hour.
2. If the material carbon equivalent is high, the workpiece is suitably heat-retained and slowly cooled after welding.
3, surfacing should adopt a small current, the effect is better.
D406 Hardfacing Electrode Model:EDRCrMnMoWCo-A
Description: Chrome-molybdenum-tungsten hot-strong steel wear-resistant surfacing electrode, surfacing metal a + solid solution + austenite + martensite + eutectic structure, with high red hardware, crack resistance and thermal fatigue resistance.
Uses: For high temperature cutting tools, molds, such as heat-shearing edge surfacing.
