NM450 abrasion resistant steel plates are high strength wear resistant steel produced according to Chinese technical standard GB/T 24186. NM450 abrasion resistant steel plates are mainly to provide protection for wear-resistant occasions or parts, so that the equipment life is longer, the downtime caused by maintenance is shortened, and the investment of funds is correspondingly reduced.

NM450 abrasion resistant steel plates are widely used to manucature mining machinery, coal mining machinery, environmental protection machinery, engineering machinery and so on equipment. NM450 abrasion resistant steel plates are also commonly used as high-strength structural steel with yield strength ≥ 850 MPa.
