NM500 Wear resistant plate is bimetal composite wear resistant steel plate.wear-resistant steel plate NM500 is extensively used in engineering equipment, mining machinery, coal mining equipment, environmental protection equipment, metallurgical machinery, and other products.
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.

Characteristics of NM500 Steel
NM500 steel features a uniform microstructure that enhances its mechanical properties, maintaining high impact resistance even at low temperatures. The steel's composition includes elements that improve its weldability and formability, making it suitable for harsh environments. For customers, NM500 steel provides extended service life of components due to its superior wear resistance, reducing maintenance costs and downtime. Its high strength and durability allow for thinner, lighter parts without compromising performance, leading to material and cost savings. However, the high hardness of NM500 steel makes it challenging to machine and requires specialized equipment and techniques. For applications needing easier machinability, 450HB steel is recommended, offering a balance of hardness and workability.

faq
What is NM500 steel?
NM500 is a wear-resistant steel known for its high hardness and toughness. The "NM" stands for "wear-resistant" and the "500" indicates its Brinell hardness. Originating in China, NM500 is used in industries requiring extreme abrasion resistance. It is similar to ASTM A514 steel.
What is the difference between AR500 and NM500?
AR500: Higher carbon (C: ~0.38–0.45%), chromium (Cr: ~1.5%), and boron (B: 0.0005–0.006%) for enhanced hardness and corrosion resistance . NM500: Lower carbon (C: ≤0.38%), added nickel (Ni: ≤1.0%) and molybdenum (Mo: ≤0.65%) for balanced weldability and toughness .
What is the hardness of NM 500?
With a hardness range of 470-540 HBW, NM500 is widely used in applications where resistance to abrasion is a primary concern, such as in mining equipment, construction machinery, and other heavy-duty applications.
