What is NM 450 wear steel?
NM450 wear-resistant steel plate is a high-strength wear-resistant steel plate. “N” is the abbreviation of “resistant”, “M” is the abbreviation of “wear”, and “450” represents the Brinell hardness value HB value of about 450 (the domestic NM450 hardness value is usually between 420-480HBW).

Advantages of NM 450 Wear Steel Plate
High wear resistance: high surface hardness, can effectively resist wear and scratches, can withstand heavy loads and impact loads, greatly reducing wear and maintenance costs.
Impact and fatigue resistance: can absorb a lot of energy when impacted, reduce equipment damage, and is not prone to fatigue damage after long-term use, ensuring stable operation of the equipment.
Good processing and welding performance: can easily perform processing operations such as cutting, bending, and welding, and is not prone to cracks or deformation
