Product Description:
As a professional steel exporter, CJM 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.
