AR450 Abrasion Resistant Steel Plate
Ultimate Durability for High-Impact Environments Stop frequent equipment replacements. Our AR450 abrasion resistant steel plate is engineered for applications demanding a balance of extreme hardness, toughness, and formability. With a nominal hardness of 450 BHN, it offers significantly longer service life than standard structural steel. [ Request a Rapid Quote ] | [ Download Data Sheet (PDF) ]
Why Choose AR450 Steel?
While AR400 is the industry standard, AR450 provides roughly 15% more wear life without sacrificing the ease of welding and cold bending. It is the “sweet spot” for heavy-duty equipment.
- Extended Service Life: Reduces downtime by resisting sliding and impact abrasion.
- Excellent Formability: Despite its hardness, it can be bent and formed with the right equipment.
- Superior Weldability: Compatible with standard welding processes (SMAW, GMAW).
- Cost-Effective: Higher upfront durability leads to lower Total Cost of Ownership (TCO).

Frequently Asked Questions
What is the difference between AR450 and AR500?
AR450 offers better formability and impact resistance, making it ideal for structural wear parts. AR500 is harder and better for extreme sliding abrasion but is more brittle and difficult to form.
Can AR450 be used for structural loads?
AR450 is a wear-resistant grade, not a structural grade. While it is incredibly strong, it is not recommended for primary load-bearing structural members in buildings or bridges.
