NM400A steel for crusher liners and blades

NM400A steel for crusher liners and blades

NM400A steel is pronounced as dancing wear-resistant four zero, N and M respectively represent the words "resistant" and "wearing" for wear-resistant, and 400 is the Brinell hardness value HB value. The hardness value of 400 is broad, and the range of hardness value of domestic NM400 is 360-420. He is a high-strength wear-resistant steel plate.
Performance analysis
NM400A steel plate has quite high mechanical strength, and its mechanical properties are 3 to 5 times that of ordinary low alloy steel plates. It can significantly improve the wear resistance of machinery-related parts to increase the service life of the machinery and significantly reduce production costs.
