High Strength Low Alloy AR450 Steel Plate Wear Plate

Introduction

AR450 is a high-strength low alloy wear-resistant steel plate, belonging to the abrasion-resistant (AR) steel category. The "450" denotes its approximate Brinell hardness (HB) level, indicating excellent wear resistance. It is widely used in heavy machinery, mining, construction, and transportation industries where high abrasion resistance and impact resistance are required.

Content	0.38–0.45	0.25–0.70	1.40–1.80	≤0.025	≤0.010	0.50–1.20	0.20–0.50	≤0.50	≤0.005

Key Alloying Elements:

Carbon (C): Enhances hardness and wear resistance.

Manganese (Mn): Improves hardenability and strength.

Chromium (Cr) and Molybdenum (Mo): Boost corrosion and wear resistance, stabilize microstructure.

Silicon (Si): Improves resistance to surface oxidation.

 

 

 

 

Manufacturing Process

Heat Treatment:
AR450 undergoes quenching and tempering to achieve its high hardness and toughness balance:

Quenching: Rapid cooling after austenitization to form martensite.

Tempering: Post-quenching heat treatment to reduce internal stress and improve ductility.

Production Standards:
Complies with international standards such as ASTM A514/A514M (USA), EN 10204 3.1 (Europe), or JIS G3136 (Japan).
