Abrasion Resistant Steel Plates – AR 400 / 450 / 500

High-strength abrasion-resistant (AR) steel plates AR 400, AR 450, and AR 500 are designed to provide exceptional resistance to impact, wear, and sliding abrasion. These plates are frequently utilized in applications where long service life and durability are essential in harsh environments. These grades are perfect for high-performance parts and equipment in industries including mining, construction, material handling, and recycling because they combine high hardness with good toughness and weldability. They are made for heavy-duty applications.

Available Grades and Properties:

Grade Typical Hardness Wear Resistance Toughness Best Suited For
AR 400 ~400 HBW High Excellent General purpose wear applications
AR 450 ~450 HBW Very High Very Good Components with moderate to severe wear
AR 500 ~500 HBW Maximum Moderate to Good Equipment exposed to extreme abrasion and impact

Key Features:

  • Exceptional abrasion and impact resistance

  • Long-lasting performance in aggressive environments

  • High tensile strength and structural integrity

  • Good formability and weldability

  • Reduces maintenance and operational downtime

Typical Chemical Composition (% by Weight):

Grade C Mn Si Cr Mo Ni
AR 400 0.18 1.30 0.30 0.90 0.25 0.25
AR 450 0.22 1.40 0.35 1.00 0.30 0.30
AR 500 0.26 1.50 0.40 1.10 0.35 0.35

(Values are typical and may vary depending on the manufacturer.)
