NM550 abrasion resistant plate
NM550 wear steel plate is a high-strength wear resistant steel plate with high wear resistance and Brinell hardness value of 550(HBW).NM550 wear resistant steel is mainly used to provide protection in occasions or parts where wear resistance is required to make the equipment life longer and reduce maintenance.
NM550 wear resistant steel itself has very high strength, but also has very high wear resistance, corrosion resistance, impact resistance, fatigue resistance, welding easy processing performance and cold forming properties, widely used in various industrial fields.
