The alloy layer of the NM500 abrasion resistant steel plate has high wear resistance, and the service life of the surfacing parts is relatively long, which is about eight times longer than the traditional service life. NM500 abrasion resistant steel plate generally uses flux-cored welding wire for surfacing, because the abrasion resistant steel plate does not require rust removal process, it can be surfacing directly on it, and there is no need to add other fluxes during surfacing. The whole process is relatively simple. After the surfacing welding is over, there is no need to clean up a lot of welding slag.
A small amount of alloy powder materials are used in the surfacing of NM500 abrasion resistant steel plates. These materials can ensure the high hardness of the wear-resistant liner and improve the wear resistance of the substrate. After welding, the surface is flat and the shape is also good. There is great value for practical applications .
The surfacing process of NM500 abrasion resistant steel plate has requirements for current, voltage and welding speed. These factors determine the final surfacing effect, and the diluted composition also has a decisive influence on the structure and properties of the welded layer.
