NM400 steel plate belongs to wear-resisting steel plate (wear-resisting plate) series is high strength wear-resisting steel plate. NM400 steel plate has a high mechanical strength, its mechanical properties are 3 times to 5 times of the ordinary low alloy steel plate, can significantly improve the mechanical related parts of the wear resistance, so improve the service life of NM400 steel plate, reduce the production cost.
The surface hardness of NM400 steel plate usually reaches 360 ~ 450HB. Used for mining and all kinds of construction machinery wear-resistant parts processing and manufacturing applicable structural steel plate.
The delivery status of NM400 steel plate is divided into: quenching and tempering (that is, quenching and tempering) PS: the specific delivery status should be indicated in the contract. NM400 steel plate packing, marking and quality certificate: The packing, marking and quality certificate of steel plate shall comply with GB/T 247.
