What Is AR450 Steel Plate?
AR450 steel plate is a type of abrasion resistant (AR) steel defined primarily by its Brinell hardness range of approximately 420–470 HBW. Compared with AR400, AR450 offers higher surface hardness and improved wear resistance, while maintaining better ductility and formability than harder grades such as AR500.
AR450 steel is typically produced using controlled rolling followed by quench and temper (Q+T) heat treatment, allowing the plate to achieve enhanced surface hardness while retaining sufficient toughness in the core. This makes AR450 suitable for applications involving sliding abrasion, moderate impact, and fabrication requirements.

Key Features of AR450 Steel Plate
- Excellent resistance to sliding and gouging abrasion
- Higher hardness than AR400 with better formability than AR500
- Good weldability with proper procedures
- Reliable impact resistance under dynamic loads
- Uniform hardness and mechanical properties
- Cost-effective solution for medium-to-heavy wear environments
These advantages make AR450 steel plate an ideal material for components exposed to continuous wear while still requiring fabrication and forming.
AR450 Steel Plate Applications
AR450 steel plates are widely used in industries where abrasion resistance and structural performance are equally important:
- Mining equipment liners
- Dump truck bodies and sidewalls
- Buckets, blades, and cutting edges
- Hoppers and chutes
- Material handling and recycling systems
- Construction and earthmoving machinery
- Agricultural wear components
AR450 vs AR400 vs AR500 Steel Plate
| Grade | Hardness (HBW) | Formability | Wear Resistance | Typical Use |
|---|---|---|---|---|
| AR400 | 360–440 | Excellent | Moderate | Light-to-medium wear |
| AR450 | 420–470 | Good | High | Balanced wear & forming |
| AR500 | 460–540 | Limited | Very High | Severe abrasion |
When both wear resistance and fabrication are required, AR450 steel plate is often the most practical and economical choice.
Welding & Fabrication Notes
- Use low-hydrogen welding consumables
- Preheating may be required depending on plate thickness
- Avoid excessive heat input to preserve hardness
- Machining and grinding are not recommended unless necessary
- Proper welding procedures ensure structural integrity without compromising abrasion resistance.

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.
