AR600 vs AR500: What Is the Difference in Hardness and Wear Resistance?
When discussing AR600 vs AR500, hardness is the most obvious difference.
- AR500 hardness: Approx. 470–540 HBW
- AR600 hardness: Approx. 570–640 HBW
The higher the Brinell hardness, the stronger the material's resistance to sliding abrasion. AR600 offers superior resistance to wear in high-friction environments such as aggregate handling, mining chutes, and high-speed material transfer systems.
However, higher hardness also means increased brittleness. While AR600 performs exceptionally in low-impact, high-abrasion conditions, AR500 provides a better balance between wear resistance and toughness. For many industrial applications, AR500 remains the most versatile and widely used abrasion-resistant plate.
Key Insight on AR600 vs AR500 Performance
If your application involves extreme abrasion with minimal impact (e.g., fine particle sliding), AR600 may outperform AR500. If your equipment faces heavy impact or dynamic loads, AR500 may be the safer and more cost-effective option.
Is AR600 Better Than AR500 for Mining Applications?
In mining operations, wear plates are subjected to both abrasion and impact. So, is AR600 better than AR500 in mining?
It depends on the specific equipment:
- Dump truck liners & crusher liners: AR500 is often preferred due to better impact resistance.
- Transfer chutes & fine material liners: AR600 may provide longer service life.
- Bucket liners in high-impact zones: AR500 is generally safer.
From our export experience at GNEE, most mining customers choose AR500 for structural wear areas and selectively use AR600 for high-wear zones where impact is controlled.

AR600 vs AR500: Toughness and Weldability Comparison
One important factor when evaluating AR600 vs AR500 is fabrication performance.
Toughness
- AR500 offers superior impact resistance.
- AR600 is harder but less ductile.
Higher hardness steels like AR600 require more careful handling during cutting and forming. Improper processing may lead to cracking.
Weldability
AR500 has better weldability compared to AR600.
Both require:
Preheating before welding
Low-hydrogen electrodes
Controlled heat input
For complex fabrication or structural components, AR500 is usually more fabrication-friendly.
At GNEE, we provide technical guidance on welding parameters and can supply pre-cut, pre-drilled, or CNC-processed wear plates according to customer drawings.
Is AR600 Better Than AR500 in Cost and Service Life?
From a purchasing perspective, cost-effectiveness matters.
- AR600 price: Higher due to advanced alloying and heat treatment.
- AR500 price: More economical and widely available.
Service Life Consideration
AR600 may last longer in pure abrasion conditions, but if cracking occurs due to impact, replacement costs increase. Therefore, "better" does not always mean "harder."
Our recommendation: Conduct a wear environment assessment before deciding. GNEE's engineering team can analyze your working conditions and recommend AR500 or AR600 accordingly.
