01Product Overview & Specifications
NM500 is a premium high-hardness abrasion-resistant steel plate manufactured per the GB/T 24186 Chinese standard, featuring a standard hardness of 500 HBW. It is specially designed for extreme wear working scenarios that require superior abrasion resistance paired with reliable cold bending performance and excellent weldability — balanced mechanical properties enable NM500 to adapt to high-intensity friction and heavy impact loads stably.
As an upgraded high-strength wear-resistant steel grade, NM500 delivers far stronger anti-wear performance than ordinary carbon steel and conventional NM400/NM450 steel plates. It effectively protects vulnerable wear parts of industrial equipment, greatly extending equipment service life, reducing frequent maintenance and repair costs, and lowering overall capital investment and operating losses for industrial enterprises.

Q1What is NM500 steel plate?
NM500 is a premium high-hardness wear-resistant steel plate per the GB/T 24186 Chinese standard, featuring a standard hardness of 500 HBW (range 480–520 HBW). It is specially designed for extreme wear working scenarios requiring superior abrasion resistance, reliable cold bending performance and excellent weldability.
Q2What is the international equivalent of NM500?
NM500 corresponds to AR500 (ASTM) and DILLIDUR 500V (DIN); SSAB Hardox 500 is its best-known international counterpart. Please confirm welding, bending and cutting parameters per actual project requirements before material replacement.
Q3What thickness and sizes are available?
NM500 plates come in 3–120mm thickness, standard widths 1500 / 1800 / 2000 / 2500mm and standard lengths 6000 / 8000 / 10000mm; custom sizes and shapes are available on request.
Q4What are the mechanical properties of NM500?
Per GB/T 24186: Brinell hardness 480–520 HBW (typical 500 HBW), with ultra-high abrasion resistance, excellent cold bending performance, reliable weldability and stable structural strength — maintaining stable mechanical performance under long-term high-intensity abrasion and heavy impact loads.
Q5What is your MOQ and delivery time?
MOQ is 1 ton (negotiable). Stock plates ship in 3–7 days; custom production takes 15–30 days depending on sizes and processing requirements.
Q6What is the difference between NM500 and NM450?
NM500 delivers upgraded hardness (480–520 HBW vs 420–480 HBW) and far stronger anti-wear performance than conventional NM450, adapting to extreme wear working conditions with high-intensity friction and heavier impact loads. For parts suffering severe abrasion, upgrading from NM450 to NM500 further extends equipment service life and lowers maintenance and repair costs — both grades are supplied from stock at 3–120mm thickness.
