NM500 High-strength Wear-resistant Steel Plate for Engineering Machinery
NM500 steel is a wear-resistant steel with a hardness of 500 HB. It is generally used in extremely high wear and high impact environments and is widely used in engineering machinery, mining machinery and coal mining equipment.
The initial cost of NM500 is 50-80% higher than that of ordinary steel plates, but it can reduce overall maintenance costs by 40-60% over its lifespan. Therefore, it is widely used in core wear-resistant components in industries such as mining, construction machinery, and metallurgy.

Features of NM500 Wear-resistant Plate
1.High strength and hardness: able to withstand high-intensity pressure and friction, not easily worn. Its tensile strength reaches over 500MPa and its hardness value reaches HBW500.
2.Good toughness: Even with high hardness, NM500 wear-resistant plate still maintains a certain toughness, which can reduce the occurrence of cracks while bearing high impact loads.
3.Impact resistance: It has excellent impact resistance and can meet various mechanical processing and manufacturing needs.
4.Corrosion resistance: After special treatment, it has good corrosion resistance and can resist the erosion of chemical substances such as acid, alkali, salt, etc.

FAQ:
What is NM500 steel?
NM500 Steel is one steel grade in GB standard GB 24186. NM 500 steel is a high-strength, wear-resistant / abrasion resistant steel known for its superior hardness and durability. This steel is specifically designed to withstand high wear conditions and provide extended service life in challenging environments.
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 are the properties of NM500 material?
NM500 is a high-strength wear-resistant steel composed of approximately 89% iron, 0.26% carbon, and alloying elements like chromium, molybdenum, and nickel. It is supplied as solid, hot-rolled plates. Known for high hardness and toughness, NM500 offers excellent abrasion resistance.
