The wear life of NM500 wear-resistant steel plate is two to three times that of NM400, which is very popular in the market.
Due to the difference of its production process, NM500 steel plate is divided into two different types according to its thickness. The thickness of the sheet is between 2mm and 6.5mm, and the hardness HBW is between 470 and 530. Although the internal hardness of the steel plate is slightly lower than that of the surface, the overall quenching process makes the internal center hardness not low, which can reach 90% of the surface. The thickness of thick plate is 4mm to 35mm, the hardness is the same as that of thin plate, and the yield is 1400MPa, which can maintain good mechanical properties.
NM500 wear-resistant steel plate can be cut by flame, plasma, laser and water knife. The most important thing to pay attention to is rolling. Because NM500 steel plate has high hardness and high yield, it has high requirements for equipment. If not, the steel plate can be preheated and chamfered, which is easier to carry out.
