NM500 VS AR500 Wear-resistant steel plate

play a vital role in many industries, especially in those environments that require high-intensity friction and impact. NM500 and AR500 are two widely used wear-resistant steel plates, each with its own characteristics in terms of hardness, wear resistance, impact resistance, etc. So what is the difference between them? This article will explore the difference between NM500 and AR500 from multiple angles, and I hope it will be helpful to everyone.

Origin: NM stands for "wear-resistant" in the Chinese standard GB/T24186.

Hardness: Typically around 500 HBW (Brinell Hardness).

Abrasion Resistance: Excellent resistance to wear and abrasion, suitable for high-wear applications.

Strength: High tensile strength and toughness properties.

Manufacture: Produced according to the Chinese standard GB/T24186.

Origin: AR stands for "Abrasion Resistant" steel grade.

Hardness: Generally around 500 BHN (Brinell Hardness Number).

Abrasion Resistance: Known for its exceptional resistance to sliding wear and impact.

Strength: Offers good strength and toughness characteristics.

Manufacture: Typically produced according to ASTM International standards (e.g., ASTM A514 or ASTM A572).

Both NM500 and AR500 have similar hardness levels, usually around 500 HBW or 500 BHN.

Both grades offer excellent abrasion resistance, making them suitable for applications where wear and tear are significant concerns.

Both NM500 and AR500 provide good strength properties, enabling them to withstand high-impact and abrasive environments.

NM500 is manufactured based on the Chinese standard GB/T24186, while AR500 is typically produced following ASTM International standards or other equivalent specifications.

Common applications for both NM500 and AR500 include mining equipment, dump truck bodies, construction machinery, and any application requiring wear-resistant materials in harsh operating conditions.

Depending on your location and specific requirements, the availability of NM500 or AR500 steel plates may vary. Local suppliers and distributors can provide information on sourcing these materials.

Generally, if the application scenario requires long-term friction and wear and lighter impact, it is recommended to choose NM500. If the application scenario involves high-intensity impact or even bulletproof requirements, AR500 is a more suitable choice.

If the budget is limited, but high wear resistance is required, NM500 is a cost-effective choice. If the budget is sufficient and strong impact resistance and wear resistance are required, AR500 may be more in line with the needs.

Different suppliers may have differences in product quality, production scale and price. It is crucial to choose a reliable supplier.

Although NM500 and AR500 have similar hardness, they have significant differences in performance. NM500 focuses more on wear resistance and is suitable for heavy-load wear environments, while AR500 is good at impact resistance and is widely used in protection, military and high-impact working environments. Choosing the right material requires comprehensive consideration of multiple factors such as specific application scenarios, budget, and suppliers.

Is NM500 the same as AR500 steel?

AR500 is preferred in North America for compliance with ASTM certifications, while NM500 dominates Asian markets . Both steels exceed 500 HBW surface hardness, but AR500 shows marginally higher tensile/yield strength and better low-temperature toughness .

Is Hardox 500 the same as AR500?

Differences Between Hardox and AR500
One of the most significant differences is their hardness level. Hardox grades usually range from 400 to 600, while AR500 has a hardness level 500. Hardox has high toughness and tensile strength and can handle a wide range of extreme temperatures compared to AR500.

What is the difference between Hardox 500 and NM500?

NM500 exhibits a hardness that typically fluctuates between 470-540 HBW, slightly edging out Hardox 500, which generally hovers around 470-530 HBW. This hardness is a key indicator of their prowess in withstanding the effects of abrasive wear and impact.

Why is AR500 steel so expensive?

AR500 steel is generally more expensive than other types of steel due to . However, its durability and resistance to abrasion make it a cost-effective choice for applications where other materials may wear out quickly.
