Nm500 Abrasion Wear Resistant Steel Plate Sheet
M is the first pinyin letter for "wear" in "wear".
500 is the Brinell Hardness number HB value. (500 hardness value is a broad sense, the domestic NM500 hardness value is about 500.)
NM500 wear-resistant steel plate is widely used in engineering machinery, environmental protection machinery, metallurgical machinery, abrasive tools, bearings and other product parts.
NM500 is a high-strength wear-resistant steel plate, which has a high wear resistance, Brinell hardness value of 500 (HBW) is mainly in the need of wear-resistant occasions or parts to provide protection, so that the equipment life is longer, reduce the maintenance and downtime brought by maintenance, and correspondingly reduce the investment of funds.
