Abrasion Resistant Plates – Rock Star 400 / 450 / 500

Premium-grade abrasion-resistant (AR) steel plates, Rock Star 400, 450, and 500 are designed to function remarkably well in settings where durability and high wear resistance are essential. In order to provide exceptional mechanical strength, excellent surface toughness, and prolonged wear life under the most severe situations, these plates are made utilizing sophisticated metallurgical methods. Regardless of your industry—mining, earthmoving, building, recycling, cement, or quarrying—Rock Star AR plates provide the durability and functionality you require to lower maintenance expenses and downtime.

Available Grades & Properties:

Grade Typical Hardness (HBW) Highlights Primary Uses
Rock Star 400 ~400 HB Excellent balance of wear resistance and formability Liners, hoppers, earthmoving equipment
Rock Star 450 ~450 HB Increased hardness and impact resistance Dump truck bodies, buckets, feeders
Rock Star 500 ~500 HB Maximum hardness for extreme wear conditions Shredder parts, crusher liners, cutting edges

Key Features:

  • Outstanding abrasion and wear resistance

  • Uniform hardness distribution throughout the thickness

  • High impact toughness, even in low temperatures

  • Enhanced machinability, weldability, and cold formability

  • Long service life, reducing repair and replacement frequency

Mechanical Properties:

  • Hardness Range:

    • Rock Star 400: 360–440 HBW

    • Rock Star 450: 420–480 HBW
