AR450 Wear Resistant Steel Plate

Product Overview

AR450 Wear Resistant Steel Plate is a quenched and tempered abrasion-resistant steel with a typical hardness of 420–470 HBW.
It is engineered for high wear + medium impact working environments, providing an optimal balance between hardness, toughness, weldability, and fabrication performance.
Compared with standard structural steel, AR450 significantly extends service life in heavy-duty equipment, reducing maintenance frequency and total operational cost (TCO).
Youcheng Steel supplies AR450 plates with stable hardness control, strict quality inspection, and export-grade packaging to support global mining, construction, and bulk material handling projects.

WHY AR450 STEEL PLATE

Best Balance Between Cost and Performance
AR450 provides higher wear resistance than AR400 while maintaining better toughness than AR500.

Longer Service Life
Extends equipment lifetime by 2–4 times in abrasive conditions.

Reduced Maintenance Cost
Minimizes downtime, replacement frequency, and operational interruption.

Stable Industrial Quality
Uniform hardness distribution ensures consistent performance across the entire plate.
