GB/T24186 NM450 abrasion resistant plate Specification

NM450 high strength wear-resistant steel, NM450 is a wear-resistant steel.

N is a "wearable" in the "resistance" of the first phonetic alphabet. M is "wearable" in the "grinding" the first phonetic alphabet.

450 Brinell hardness HB value. (450 hardness is a broad, domestic NM450 hardness value is around 450.)

NM450 is to provide in the need to wear the occasion or parts of protected equipment, longer life, reduced maintenance and downtime caused by maintenance, into a corresponding reduction of capital.
