When comparing NM500 wear resistant steel plate with AR500, the first difference lies in their naming and standards.
AR500 stands for "Abrasion Resistant 500," which is a commonly used commercial term in North America and international markets. It is often produced according to ASTM-related practices or proprietary mill standards.
NM500 wear resistant steel plate
NM500, on the other hand, is a clearly defined grade under China's GB/T 24186 standard, where "NM" refers to "Nai Mo" (wear resistant steel).
Although the naming systems differ, both materials share one critical feature:
the "500" indicates a target hardness of approximately 500 HBW (Brinell Hardness).
NM500 vs AR500 Hardness and Wear Performance
From a mechanical standpoint, both NM500 and AR500 belong to quenched and tempered steels, designed specifically for high-abrasion environments.
| Property | AR500 Steel | NM500 Steel |
|---|---|---|
| Hardness (HBW) | 470–530 | 470–540 |
| Heat Treatment | Quenched & Tempered | Quenched & Tempered |
In real-world applications, such as mining liners or heavy equipment wear parts, the difference in hardness range is minimal. As a result, both steels deliver very similar wear resistance performance.
In most cases, NM500 can achieve nearly the same service life as AR500, making them interchangeable in the majority of industrial scenarios.
NM500 vs AR500 Chemical Composition
Both NM500 and AR500 rely on alloying elements such as chromium (Cr), nickel (Ni), molybdenum (Mo), manganese (Mn), and boron (B) to enhance hardenability and strength.
While the exact composition may vary slightly depending on production methods, the final mechanical properties-especially hardness, wear resistance, and toughness-are largely aligned.
This is why, from a performance perspective, NM500 and AR500 are considered equivalent materials in most applications.
NM500 Applications Compared to AR500
Because of their similar properties, NM500 and AR500 are widely used in the same industries and components.
In mining operations, both are used for liners, crusher plates, and chute systems where continuous abrasion occurs. In construction and heavy equipment, they are commonly applied in excavator buckets, loader attachments, and concrete mixers.
Additionally, AR500 is often used in shooting targets due to its hardness, and NM500 can serve the same purpose with comparable performance.
Cost Of NM500 vs AR500
While performance is nearly identical, the biggest difference between NM500 and AR500 lies in cost.
| Factor | AR500 Steel | NM500 Steel |
|---|---|---|
| Performance | High | Equivalent in most uses |
| Price | Higher | 30%–40% lower |
| Interchangeability | Yes | Yes |
In practical terms, choosing NM500 allows buyers to achieve the same functional performance while significantly reducing material costs. For large-scale projects, this difference can have a major impact on the total budget.

Instead of paying a premium for branding or regional supply factors, many buyers are now focusing on overall value and return on investment.
When Should You Choose NM500 Instead of AR500?
For most heavy-duty applications involving abrasion-such as mining, construction, and material handling-NM500 provides a highly efficient alternative.
If your project does not require a specific regional certification tied to AR500, switching to NM500 can be a strategic decision that balances performance and cost.
If you are looking for a cost-effective alternative to AR500 with comparable performance, NM500 wear resistant steel plate is a proven solution.

What is the difference between Hardox 500 and NM500?
Hardness: NM500 typically has a hardness range of around 470-540 HBW (Brinell hardness), while Hardox 500 typically falls within the range of 470-530 HBW. The hardness level indicates their ability to withstand abrasive wear and impact.
What is NM500 material?
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?
Key implication: 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 .
