What are the advantages of P20 wear-resistant steel?

P20 wear-resistant steel plate has many advantages. It belongs to low-carbon and low-alloy aluminum-manganese steel. After special heat treatment, it reaches a certain hardness. It not only has high hardness and wear resistance, but also fully considers welding and thermal cutting. Performance, bending performance and machinability. P20 wear-resistant steel plate has better welding. Compared with medium carbon steel, high carbon steel and other materials, the preheating temperature is lower before welding and the crack resistance is better. Generally, post heat treatment is not required after welding.

If the weld is also required to have the same hardness, flux-cored wire can be surfacing on the surface, and the surfacing layer has a very high hardness. In this case, post heat treatment should be performed after welding. The wear test shows that the wear resistance of steel wear is better than that of low alloy structural steel under low-stress abrasive wear. In actual production, the accuracy of flame-cut parts using high-hardness and wear-resistant steel plates is much higher than that of high-manganese steel and other castings, which is beneficial to the improvement of welding assembly accuracy and the appearance quality of structural parts.
