GB/T24186 NM400 steel plate for abrasion resistant plate

GB/T24186 NM400 steel plate for abrasion resistant plate

GB/T24186 NM400 steel plate is a high strength wear-resistant steel plate. NM400 has high mechanical strength, its mechanical properties are 3 to 5 times of that of ordinary low alloy steel plate, and the wear resistance of mechanical related parts can be significantly improved.

Therefore, the service life of the machine is improved and the production cost is reduced. The surface hardness of GB/T24186 NM400 steel plate usually reaches 360-450HB. GB/T24186 NM400 steel plate is used in the processing and manufacturing of wear-resistant and vulnerable parts for mining and various construction machinery.
