As a professional steel exporter, GNEE Steel supplies a full range of abrasion resistant steel plates, including AR400, AR450, and AR500 steel plates. These high-strength wear-resistant plates are widely used in industries such as mining, construction, material handling, and heavy equipment manufacturing.
What Is AR Steel Plate?
AR steel refers to Abrasion Resistant steel, a category of high-carbon alloy steel designed to resist wear and abrasion under tough conditions. The numbers (400, 450, 500) represent the average Brinell Hardness Number (BHN). The higher the number, the more hardness and wear resistance the plate offers.
AR400 steel plate: Balanced strength and toughness, ideal for buckets, dump liners, and structural wear parts.
AR450 plate: Enhanced hardness for increased resistance against sliding wear.
AR500 plate: Excellent performance in extreme conditions like shooting targets, hoppers, and impact zones.

What is the difference between AR400 and AR450 steel?
AR400 vs. AR450: With an HBW of 430-480, AR450 is slightly harder and more wear-resistant than AR400 but maintains similar It is not as easy to weld or form as AR400 but is more formable than AR500.
Is AR400 stronger than AR500?
The main differences are hardness and strength, achieved through varying levels of carbon and manganese. AR500 is slightly stronger (in terms of tensile strength) than 400, by about 20-25%. 500 also has a higher hardness. Whereas 400 can be between 360 and 440 Brinell, 500 is between 477 and 550.
What is AR450 steel used for?
AR450 Steel Plate is used in a wide range of industries where components face abrasive contact and impact loading. Common applications include: Loader and excavator bucket liners. Dump body and truck bed liners.
Can you drill a hole in AR500 steel?
Yes, you can drill AR500 steel, but it's very difficult and requires specific tools, slow speeds, significant force, and heavy lubrication, with carbide-tipped masonry bits or specialized carbide bits often recommended for home setups, while industrial setups might use annular cutters or thread milling. The process is tough on tools, so expect wear, and ensure your drill press is rigid to prevent bit chatter and breakage.
