Product Overview
AR400 Wear Resistant Steel Plate is a quenched and tempered high-performance abrasion resistant steel designed for extreme wear + moderate impact working environments.
With a typical hardness of 360–444 HBW, AR400 is widely used in industries where equipment failure is caused by continuous material abrasion, not structural load failure.
Why Choose AR400?
Reduce Total Operating Cost
Extends equipment service life by 2–3 times compared with mild steel
Balanced Hardness & Toughness
Better crack resistance than AR450 / AR500 in impact environments
Lower Replacement Frequency
Reduces maintenance shutdown and labor cost
Easy Fabrication
Supports cutting, welding, bending, and machining
