NM500 abrasion resistant steel plate

GB/T24186 NM500 abrasion resistant steel plate is an abrasion resistant plate with a hardness of 500 HBW. intended for applications where demands are mposed on abrasion resistance in combination with good cold bending properties. GB/T24186 NM500 abrasion resistant steel plate offers very goodweldability.

GB/T24186 NM500 abrasion resistant steel plate is a high-strength wear-resisting steel plate, which has a high abrasion resistance. Brinell hardness value up to 500(HBW) is mainly used to provide protection for wear-resisting occasions or parts, so as to prolong the service life of the equipment, reduce the maintenance and stop caused by maintenance, and correspondingly reduce the investment of funds.
