Frequently Asked Questions

Learn more about AR Medium steel plate.
Abrasion-resistant steel plate is primarily selected by hardness and wear performance, not by one fixed chemical formula. Because of that, chemistry and hardening processes can vary by mill as long as the plate meets the required hardness range and performance expectations for the grade. Mill test reports or hardness reports are supplied with orders to verify the material’s properties and confirm it meets the specified AR grade.
AR Medium plate is designed for moderate wear applications and includes grades such as AR200 and AR235. AR400 is a harder abrasion-resistant plate used for more demanding wear applications. The main difference is hardness: AR Medium sits in a lower hardness range, while AR400 is used when greater abrasion resistance is required.
AR Medium steel plate is used for moderate wear applications where abrasion resistance is needed, but structural or load-bearing performance is not required. Common AR Medium use cases include material chutes, material-moving equipment, truck liners, bulk material handling liners, skirt board liners, cement mixer components and screw conveyors.
No. AR Medium steel plate is not intended for structural or load-bearing use. It is designed for moderate wear resistance, meaning it is used where abrasion, sliding or scraping are the main concerns rather than structural strength.
AR Medium is a general name for moderate-wear abrasion-resistant plate, and AR200 and AR235 are common AR Medium grades. The numbers generally refer to expected Brinell hardness levels, with AR200 around the 200 BHN range and AR235 around the 235 BHN range. Both are used for moderate wear applications rather than structural applications.
BHN stands for Brinell hardness number, a measurement used to describe surface hardness. For AR Medium plate, hardness is especially important because abrasion-resistant grades are selected by wear resistance and hardness rather than structural design properties. Leeco® supplies surface hardness reports with each AR Medium order.
