When to avoid using thermal cutting in NM400 wear-resistant steel plate processing

Steel plate is a very hard material, but it can be processed by certain methods. The hardness of NM400 wear-resistant steel plate reaches 400HB, which is very resistant to wear. This kind of material plays an important role in engineering construction, but such good properties create restrictions in the process of processing. So we need to choose the right method when cutting NM400 steel plate.

Ordinary steel may be cut with a slightly harder cutter, but the NM400 wear-resistant steel plate is different. It can be cut by laser or hot cutting. However, it is not always possible to use thermal cutting, such as when processing thin steel plates. Thermal cutting saves time, effort and money, but waste.

During thermal cutting, the edge part of the NM400 wear-resistant steel plate will deform to a certain extent, causing the material in this part to be scrapped. The thinner the steel plate, the more such a situation will occur. For thicker NM400 wear-resistant steel plates, you can safely use thermal cutting, while thin plates can choose laser cutting or plasma cutting. This processing method is not suitable for thick plates, because the resulting chamfered surface will also cause some loss.
