AR600 steel plate
Within the first 100 words, it is essential to clarify our role. GNEE is a manufacturer and global supplier of wear resistant steel plates, providing factory-direct AR600 plate solutions for mining, concrete, aggregate, and heavy industrial applications where ultra-high hardness steel is required.
AR600 steel plate combines exceptional abrasion resistance with controlled toughness, enabling extended service life even under severe sliding and impact wear.
Key Properties of AR600 Quenched and Tempered Steel Plate
AR600 steel plate achieves its performance through controlled quenching and tempering. This heat treatment produces a hardened surface with consistent through-thickness hardness.
Key performance characteristics include:
- Excellent abrasion and wear resistance
- Ultra-high surface hardness
- Reliable toughness at low temperatures
- Suitability for laser cutting and plasma cutting
- Limited but controlled bending capability
- Stable flatness and dimensional accuracy
These properties make AR600 suitable for applications where softer AR grades are no longer sufficient.

Fabrication, Welding and Post-Delivery Heating Guidelines
-
Cutting and Fabrication
AR600 steel plate performs well in laser cutting and plasma cutting operations. Tool wear may be higher due to extreme hardness.
-
Bending
Bending capability depends on plate thickness, radius, and application conditions. Large bend radii are recommended. Please consult technical support before forming.
-
Welding
AR600 can be welded using conventional processes such as:
SMAW
SAW
GMAW
Low-hydrogen welding consumables and qualified welding procedures are required to reduce cracking risk.
-
Post-Delivery Heating
Post-fabrication heating or stress relieving must not exceed 300°F (150°C). Higher temperatures may reduce hardness and mechanical strength.
Typical Applications of AR600 Steel Plate
AR600 steel plate is widely used in industries where extreme wear resistance is critical.
Common applications include:
Mining equipment liners
Aggregate and concrete processing systems
Chutes, hoppers, and feed bins
Wear plates for crushers and screens
High-abrasion industrial components

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.
