Understanding the difference between AR 400 vs. AR 500 steel plates is essential when selecting wear-resistant materials for mining, construction, and heavy-duty equipment. As a professional wear resistant steel plate manufacturer, GNEE Steel helps global customers choose the right abrasion-resistant steel based on application, service life, and cost efficiency.
Within the first stages of material selection, engineers often compare AR 400 steel plates and AR 500 steel plates to balance hardness, toughness, and fabrication performance. This guide explains the key differences clearly-directly from the manufacturer's perspective.

AR 400 Steel Plates – Properties, Hardness, and Applications
AR 400 steel plates typically have a Brinell hardness of 360–440 HB, offering an excellent balance between wear resistance and impact toughness. This makes AR 400 a widely used grade in moderate-abrasion environments.
Key Characteristics of AR 400 Steel Plates
- Good abrasion resistance
- Better formability and weldability
- Lower cracking risk during fabrication
- Cost-effective for medium-wear applications
Typical Applications of AR 400 Steel Plates
- Dump truck bodies
- Hoppers and chutes
- Conveyors
- Construction equipment

AR 500 Steel Plates – Higher Hardness for Severe Wear Conditions
AR 500 steel plates are designed for extreme abrasion, with a typical hardness range of 470–530 HB. This higher hardness significantly extends service life in high-wear environments but requires more attention during fabrication.
Key Characteristics of AR 500 Steel Plates
- Superior abrasion resistance
- Longer service life under sliding wear
- Higher strength but reduced formability
- Requires controlled welding procedures
Typical Applications of AR 500 Steel Plates
Mining liners
- Quarry crusher liners
- Cement plant wear parts
- Heavy-duty buckets and blades

AR 400 vs. AR 500 Steel Plates – Key Differences Comparison
When comparing AR 400 vs. AR 500 steel plates, the core differences lie in hardness, wear resistance, and fabrication behavior.
AR 400 vs. AR 500 Steel Plates Comparison Table (Conceptual)
- Hardness: AR 500 > AR 400
- Wear Resistance: AR 500 offers longer service life
- Formability: AR 400 is easier to bend and weld
- Cost: AR 400 is more economical
- Application Severity: AR 500 suits harsher wear
Choosing a harder plate does not always mean better performance-improper selection may increase fabrication costs or cracking risks.
How to Choose Between AR 400 and AR 500 Steel Plates
Selecting between AR 400 vs. AR 500 steel plates should be based on real operating conditions rather than hardness alone.
Consider the following factors:
- Type of abrasion (sliding vs. impact)
- Operating temperature
- Required service life
- Fabrication and welding capabilities
- Budget constraints
GNEE Steel's technical team evaluates these parameters and provides application-based material recommendations to optimize cost and performance.
