Are you searching for high-performance wear-resistant steel for heavy-duty industrial applications? AR500 steel is the industry-leading solution, and you've partnered with the right manufacturer.
As a top Chinese supplier of wear-resistant steel with 18+ years of experience, GNEE produces ASME-compliant AR500 steel plates that deliver exceptional durability and cost efficiency.
In this guide, we'll break down the critical properties of AR500 steel and its key applications, helping you determine if it's the right choice for your project.
Core Properties of AR500 Steel That Drive Performance
The superior performance of AR500 steel stems from its carefully engineered properties, which balance hardness, toughness, and wear resistance-critical for withstanding harsh industrial conditions.
Key Mechanical Properties
- Hardness: Minimum 500 Brinell Hardness (HB), achieved through quenching and tempering. This hardness level is 2–3x higher than standard carbon steel, making it highly resistant to abrasive wear.
- Tensile Strength: 1,800–2,200 MPa (261–319 ksi), ensuring it can withstand high impact loads without cracking-unlike brittle high-hardness steels.
- Impact Toughness: ≥20 J at -40°C (-40°F), providing reliable performance in cold environments (e.g., mining operations in northern regions).
- Weldability: Controlled carbon content (≤0.25%) and alloy additions (chromium, molybdenum) enable welding with low-hydrogen electrodes, simplifying fabrication.
Chemical Composition Highlights
AR500 steel's composition is optimized for wear resistance:
- Carbon (C): 0.20–0.25% (enhances hardness)
- Chromium (Cr): 1.00–1.50% (improves corrosion and wear resistance)
- Manganese (Mn): 1.00–1.50% (boosts tensile strength)
- Molybdenum (Mo): 0.20–0.40% (enhances toughness and heat resistance)

Key Applications of AR500 Steel Across Industries
AR500 steel's unique property combination makes it versatile across multiple industries, particularly where abrasion and impact are primary concerns.
Below are its most common high-value applications:
1. Mining and Quarrying
Equipment Components: Crusher liners, conveyor idlers, ore chutes, and screen panels. AR500 steel extends component lifespan by 3–5x compared to standard steel, reducing maintenance downtime.
Use Case: A coal mining client in Australia reported that AR500 crusher liners lasted 12 months-up from 3 months with their previous steel grade.
2. Construction and Heavy Machinery
Machinery Parts: Excavator bucket teeth, bulldozer blades, and skid steer loader buckets. These parts face constant abrasion from rocks and soil, making AR500 steel's hardness critical.
Road Construction: Asphalt paver screeds and concrete mixer drums, where resistance to aggregate wear is essential for long service life.
3. Transportation and Logistics
Dump Truck Bodies: Lining dump truck beds with AR500 steel prevents wear from gravel, sand, and construction debris-reducing the need for frequent body replacements.
Railway Applications: Railway ballast cleaners and track maintenance equipment, where AR500's toughness withstands heavy vibration and impact.
4. Waste Management
Waste Processing Equipment: Shredder blades, garbage truck bodies, and recycling facility conveyors. AR500 steel resists both abrasion and corrosion from wet waste, a common issue in this sector.

Why Choose GNEE's AR500 Steel for Your Projects?
As a specialized AR500 steel manufacturer, GNEE offers unique advantages that ensure you get the best value and performance for your investment:
- Strict Quality Control: Every AR500 steel plate undergoes 100% ultrasonic testing (UT) to detect internal defects, plus hardness testing at multiple points to ensure uniform performance.
- Customization Options: We provide cut-to-size plates (thickness: 6mm–100mm, width: 1,500mm–3,000mm) and pre-fabricated components (e.g., welded chutes) to reduce your on-site fabrication time.
- Global Certification: Our AR500 steel meets international standards (ASTM A514, EN 10025-4) and can be certified by SGS/BV upon request-critical for export projects.
- Fast Delivery: 7–10 day lead time for standard sizes, with expedited options available for urgent projects (e.g., equipment breakdown replacements).
Practical Tips for Working with AR500 Steel
To maximize the performance of AR500 steel in your applications, follow these key guidelines:
- Welding: Use low-hydrogen electrodes (e.g., E11018-G) and preheat plates thicker than 12mm to 150–200°C (302–392°F) to prevent cracking.
- Cutting: Plasma cutting is recommended for precision; avoid oxy-fuel cutting for plates thicker than 25mm, as it can reduce hardness in the heat-affected zone.
- Fabrication: Form AR500 steel at room temperature-cold forming preserves its hardness, while hot forming (above 300°C / 572°F) may reduce performance.
- Maintenance: Apply a corrosion-resistant coating (e.g., epoxy paint) for outdoor applications to extend lifespan, even though AR500 steel has inherent corrosion resistance.

What is AR500 Steel?
Much like AR450 and AR400, AR500 steel is a specific type of abrasion resistant steel with a surface hardness of 477-534 BHN. It is a high-carbon steel alloy that provides greater impact and sliding abrasion resistance by comparison.
How bulletproof is AR500 steel?
A thickness of 6.5 mm of AR500 is typically sufficient to protect against a NATO standard 5.56 mm caliber bullet, the SS109. Once processed, AR500 armor can be rated at NIJ Level III, designed to withstand fire from 7.62×51 mm rounds.
What does AR in AR500 mean?
Abrasion Resistant
The "AR" in AR500 steel stands for Abrasion Resistant, and the number following it represents the Brinell Hardness Number (BHN). AR500 typically falls within the 460–544 BHN range.
What are the disadvantages of AR500 steel?
AR500 Armor Level III+
Advantages: High durability, can withstand multiple impacts in the same location. Disadvantages: Steel plates are significantly heavier and prone to dangerous spalling (bullet fragmentation).
Does AR500 rust easily?
Yes. Despite its hardness, AR500 is still carbon steel and will rust if exposed to moisture and air. To protect AR500 parts, coatings are recommended: Powder coating: Available in-house at SendCutSend, adds a durable, chip-resistant protective layer.
