NM400 is a high strength wear-resistant steel plate. NM400 has quite high mechanical strength; Its mechanical properties are 3 to 5 times that of ordinary low-alloy steel plates; It can significantly improve the wear resistance of mechanical parts. Therefore, improve the service life of the machine; Reduce production costs. The surface hardness of the product usually reaches 360 ~ 450HB. Used in mining and various construction machinery for wear-resistant parts processing and manufacturing and other suitable structural steel plate.

Hardness is divided into: Rockwell hardness, Brinell hardness, Vickers hardness, Leeb hardness, Shore hardness, Babbitt hardness, Knower hardness, Wechsler hardness. Vickers hardness is expressed by HV, Rockwell hardness can be divided into HRA, HRB, HRC, HRD, Brinell hardness is expressed by HB[N(kgf/mm2)] (HBS\HBW) (refer to GB/T231-1984), the Brinell hardness method is often used in production to determine the hardness of annealed, normalized and tempered steel parts is not a simple physical concept. It is a comprehensive index of mechanical properties such as elasticity, plasticity, strength and toughness of materials. Hardness test according to its different test methods can be divided into static pressure method (such as Brinell hardness, Rockwell hardness, Vickers hardness, etc.), scratch method (such as Mohs hardness), rebound method (such as Shore hardness) and micro-hardness, high temperature hardness and other methods. |
