AR400 vs. AR500
AR400
- Excellent balance of wear resistance and formability
- Easier to fabricate and weld
- Suitable for moderate to high-wear environments
AR500
- Higher hardness and longer wear life
- Ideal for severe abrasion conditions
- Commonly used in mining, aggregates, and material handling applications
Material selection depends on wear conditions, impact levels, fabrication requirements, and expected service life.
Frequently Asked Questions About Abrasion Resistant Steel Plates
What is abrasion resistant steel plate?
Abrasion resistant steel plate is a hardened alloy steel designed to withstand sliding abrasion, impact, and material wear in demanding industrial applications.
What does AR400 or AR500 mean?
The "AR" stands for Abrasion Resistant, while the number refers to the approximate Brinell Hardness Number (BHN), an indicator of hardness and wear performance.
Can AR400 and AR500 be welded?
Yes. Both grades can be welded using proper procedures and preheat practices to maintain performance and structural integrity.
Can AR plate be cut, formed, or machined?
Yes. AR plate can be cut, drilled, beveled, machined, and formed depending on thickness, grade, and application requirements.
Is AR500 better than AR400?
Not always. AR500 offers greater wear resistance, while AR400 provides improved formability and fabrication flexibility. The best choice depends on the application.
How does AR plate compare to standard carbon steel?
AR plate delivers significantly greater resistance to wear and abrasion, helping reduce maintenance costs and extend equipment service life.
