AR500: “AR” stands for Abrasion Resistant or Armor, and “500” is a general grade designation indicating a Brinell hardness of approximately 500 HB. It is not tied to a single manufacturer; multiple steel mills (such as Xinsteel, Baowu, U.S. steel mills, etc.) can produce steel plates meeting this hardness requirement. The composition and manufacturing process may vary by producer. This material is commonly used in bulletproof targets, mining machine liners, and similar applications.

AR500 Steel Wear resistant steel plate – Main Characteristics
| Performance index | Typical values/range | Explain |
|---|---|---|
| Surface hardness | 470 – 540 HBW | Brinell hardness, with a measurement depth of approximately 1mm, is marked in the 400-500 HB range by some domestic standards |
| Strength of extension | ≥ 1300 MPa | The typical value is approximately 1350 MPa, which belongs to ultra-high strength steel |
| Yield strength | ≥ 1100 MPa | The typical value is approximately 1200 MPa (for reference with a thickness of 15mm). |
| Elongation at break | ≥ 8% – 10% | It reflects the plastic deformation capacity of the material before fracture |
| Impact toughness | ≥ 24 – 30 J | The Charpy V-notch impact energy at -40℃ ensures the ability to resist brittle fracture at low temperatures |
| Carbon Equivalent (CEV) | 0.50% – 0.58% | computational formulaC+Mn/6+(Cr+Mo+V)/5+(Ni+Cu)/15，Preheating is required for welding. |
| Condition of delivery | Quenching and tempering (quenching + tempering) | The martensitic structure is obtained through heat treatment to achieve high hardness and toughness |
| Main property | High wear resistance and high impact resistance | Its wear resistance is approximately 4 to 6 times that of ordinary low-carbon steel, and it also has certain weldability and cold formability |
From the microstructure perspective, this AR500 Steel Plate Sheet Coil typically employs advanced alloy design and controlled rolling and cooling processes. Its matrix structure is mostly composed of both strong and tough lamellar martensite or bainite, which provides a strong foundation for the AR500 Wear-resistant Steel Plate. At the same time, through precise addition of alloy elements (such as chromium, molybdenum, nickel, boron, etc.), high-hardness carbide particles are uniformly dispersed in the matrix. These hard phases are the main force resisting abrasive cutting and chiseling. More importantly, the purity of the AR500 Steel Plates for Abrasion Resistance is extremely high, with harmful elements such as sulfur and phosphorus being controlled at very low levels, and the grain size being significantly refined. This “clean” and fine-grained crystal structure can effectively prevent crack initiation and propagation, and is the core that endows the material with high toughness.
This AR500 Abrasion Resistant Steel Plate optimized microstructure directly determines its macroscopic properties. The AR500 Steel Plate 1/4″X 12″X 36″ high-hardness carbides ensure excellent wear resistance, while the tough fine-grained matrix endows the material with extremely high impact toughness, making it less prone to brittle fracture or shedding when subjected to intense impacts. The combination of these two elements enables the AR500 Steel Plate – 1/2″ X 24″ X 36″ to maintain wear resistance while being able to adapt to the manufacturing of complex components through processes such as bending and welding, thereby reducing the risk of cracking during use. The Wear Plate AR500 stability of its performance is also reflected in its good adaptability to low-temperature environments.

Is the domestically produced AR500 Quenched & Tempered Steel Plate of reliable quality?
yes
Why is the price of AR500 lower than that of imported wear-resistant plates?
The price of AR500 is lower than that of imported wear-resistant plates. The key lies in the fact that the domestic alternative has eliminated the costs of tariffs and logistics, and the scale effect has lowered the manufacturing costs. Moreover, “domestic AR500” is mostly a brand that is in line with the original specifications rather than an imported brand.
Can AR500 replace Hardox 500?
TIDAK
What are the differences between AR500 and AR400?
The main difference between AR500 and AR400 lies in their Brinell hardness grades (AR500 ≈ 477-555 HB, AR400 ≈ 370-430 HB).
Which is better, AR500 or Hardox 500?
It depends on the specific manufacturing process and working conditions of the manufacturer: Hardox 500 usually offers better toughness consistency, welding/bending performance, and a global quality assurance system. However, domestically produced or other countries’ AR500 can also be suitable if they have a high cost-performance ratio and are suitable for the working conditions.
What are the differences between AR500 and NM500?
The main difference between AR500 and NM500 lies in their naming system and standard classification (the former is the internationally recognized and American-style designation, while the latter is a specific brand name for Chinese national standards). However, their hardness grades and mechanical properties are basically equivalent, and they belong to the same type of quenched and tempered wear-resistant steel, which can be used interchangeably.
What are the advantages of replacing ordinary steel plates with AR500?
This kind of wear-resistant steel has an initial hardness much higher than that of ordinary structural steel. This means that when abrasive materials attempt to cut or chisel its surface, they will encounter greater resistance, and the rate of material loss will significantly slow down. Although its purchase price may be higher than that of ordinary steel, in environments with intense wear, its longer service life can reduce the material consumption and maintenance frequency per unit time. From a long-term operation perspective, it may be more economically viable.
