Wear Resistant Steel Sheet Nm500
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.
Wear Resistant Steel Sheet Nm500
500 is the Brinell Hardness number HB value. (500 hardness value is a broad sense, the domestic NM500 hardness value is about 500.)
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.
