AR450 steel plate
GNEE is a professional manufacturer and supplier of AR450 steel plates, supplying stable quality, certified mechanical properties, and factory-direct pricing.
AR450 is widely used in mining, quarrying, material-handling, and heavy-equipment liners where moderate-to-heavy abrasion and occasional impact occur. Compared with ultra-hard grades such as AR500, AR450 offers easier fabrication, lower welding risk, and a better trade-off between wear life and cost.
What Is AR450 Steel Plate?
AR450 (also written AR-450) refers to quenched and tempered, abrasion-resistant steel plates with a nominal surface hardness around 450 HBW. "AR" denotes abrasion resistant, and the numeric suffix indicates approximate Brinell hardness.
AR450 plates are through-hardened, providing wear resistance while maintaining core toughness for impact applications. Certain AR450 variants, such as AR450F, are specifically tailored for enhanced formability and weldability without sacrificing wear performance.
Typical Chemical Composition of AR450 Steel Plate
| Element | Typical (wt.%) |
|---|---|
| Carbon (C) | 0.18 – 0.26 |
| Manganese (Mn) | 1.0 – 1.6 |
| Silicon (Si) | 0.20 – 0.60 |
| Chromium (Cr) | 0.30 – 0.80 |
| Molybdenum (Mo) | 0.20 – 0.65 |
| Nickel (Ni) | 0.25 – 1.0 |
| Boron (B) | 0.001 – 0.005 |
| Phosphorus (P) | ≤ 0.025 |
| Sulfur (S) | ≤ 0.010 |
These alloying elements ensure through-thickness hardness, wear resistance, and adequate impact toughness. Always request the Mill Test Report (MTR) to verify chemistry for critical projects.
Mechanical Properties of AR450 Abrasion Resistant Steel
| Property | Typical Value |
|---|---|
| Surface Hardness | 425 – 475 HBW |
| Yield Strength (0.2% offset) | 900 – 1250 MPa |
| Tensile Strength | 1000 – 1400 MPa |
| Elongation | 10 – 22% |
| Charpy Impact | 20 – 40 J at room temperature |
| Hardness Through Thickness | >90% (typical) |
| Formability | Better than AR500; AR450F optimized for welding |
These properties make AR450 ideal for truck bodies, liners, chutes, hoppers, and conveyor wear parts where both abrasion and occasional impact occur.
AR450 Steel Plate Specifications & Sizes

AR450 vs AR500 Steel Plate
| Attribute | AR450 | AR500 |
|---|---|---|
| Hardness | 425–475 HBW | 460–540 HBW |
| Abrasion Resistance | Good | Higher |
| Impact Toughness | Better | Slightly lower |
| Fabrication & Weldability | Easier | Requires controlled procedures |
| Cost | Moderate | Higher |
| Typical Applications | Buckets, truck bodies, conveyors | Ballistic targets, extreme abrasion |
Decision Guide: AR450 is suitable for moderate-to-heavy wear with occasional impact. AR500 is reserved for extreme abrasion or ballistic applications where maximum hardness is required.
Applications of AR450 Steel Plates
Common industries and uses include:
Mining and quarrying: grinding equipment liners, crusher parts
Heavy machinery: truck bodies, dump beds, excavator buckets
Material handling: chutes, hoppers, conveyor wear parts
Recycling and slag handling: abrasion-prone surfaces
AR450 balances service life, fabrication ease, and cost, making it the industry workhorse for moderate-to-heavy wear.
AR450 Steel Plate Price 2025

What is AR600 steel plate?
AR600 steel plate is an ultra-high hardness abrasion resistant steel with a typical Brinell hardness of around 570–640 HBW. It is designed to provide exceptional wear resistance in extremely harsh working conditions where standard AR400 or AR500 plates are no longer sufficient.
What are the main applications of AR600 steel plate?
AR600 steel plate is widely used in severe abrasion environments such as mining liners, rock crushers, chutes, hoppers, dump truck bodies, quarry equipment, and heavy-duty material handling systems where impact and sliding wear are extremely high.
How does AR600 compare to AR500 steel plate?
Compared with AR500, AR600 offers significantly higher hardness and longer service life under severe wear conditions. However, AR600 has lower formability and weldability, making it more suitable for flat or minimally fabricated components rather than complex formed structures.
Can AR600 steel plate be cut or machined?
AR600 steel plate can be cut using plasma, laser, or water jet cutting methods. Conventional machining is difficult due to its extreme hardness, so carbide or ceramic tools are recommended, and water jet cutting is often preferred to avoid heat-affected zones.
What is the typical hardness of AR600 steel plate?
The typical hardness range of AR600 steel plate is 570–640 HBW, depending on plate thickness and production process. This high hardness is the key factor behind its outstanding abrasion resistance.
Is AR600 steel plate suitable for cold forming or bending?
Cold forming of AR600 steel plate is generally not recommended. Due to its ultra-high hardness and low ductility, bending can lead to cracking. If forming is required, alternative grades with lower hardness should be considered.
