AR235

Introduction

Abrasion Resistant Steel AR235 is a wear-resistant steel grade designed for applications where components are exposed to continuous friction, sliding, impact and material abrasion. With a nominal hardness of approximately 235 HBW, AR235 provides a practical combination of abrasion resistance, toughness, weldability and fabrication performance.

AR235 steel plates are commonly used in material handling equipment, mining machinery, quarrying equipment, construction machinery, agricultural machinery, conveyors, chutes, hoppers and industrial wear components.

The designation AR235 generally refers to a hardness class or commercial abrasion-resistant steel designation rather than one universally standardized chemical composition. Therefore, the exact chemical composition, mechanical properties and applicable standard should always be confirmed against the manufacturer’s specification and Mill Test Certificate (MTC).

Emirerri Steel supplies abrasion-resistant steel plates and wear-resistant materials for industrial applications where improved service life and resistance to mechanical wear are required.

AR235 Steel Specifications

AR235 Chemical Composition 

AR235 does not have one universally fixed chemical composition across all manufacturers. The alloying system is normally designed to achieve the required hardness, toughness and wear resistance.

Typical alloying elements may include:

Important: Exact chemical composition should be confirmed from the applicable material specification and MTC before engineering or fabrication.

AR235 Mechanical Properties

AR235 is primarily characterized by its hardness and abrasion resistance.

Unlike conventional structural steels, abrasion-resistant steels are often selected primarily according to hardness, wear resistance and toughness, rather than tensile strength alone.

AR23 Physical Properties

Typical physical characteristics of AR235 are broadly similar to low-alloy and carbon-alloy steel products.

Values may vary according to chemical composition, heat treatment and product specification.

Hardness of AR235 Steel

The AR235 designation is primarily associated with a nominal hardness of approximately 235 HBW.

A typical commercial product may have a hardness range around 215–255 HBW, although the guaranteed range depends on the manufacturer’s specification.

The hardness provides greater resistance to:

• Sliding abrasion

• Impact abrasion

• Material rubbing

• Scratching

• Surface wear

• Contact with bulk materials

• Repeated mechanical friction

For applications requiring substantially higher hardness, grades such as AR400, AR450 or AR500 may be considered.

AR235 vs AR200

AR235 offers a higher hardness level than AR200 and can therefore provide improved resistance to abrasive wear. AR200 may be preferable where easier fabrication and lower hardness are more important.

AR235 vs AR400

AR400 provides substantially greater hardness and abrasion resistance, while AR235 offers easier fabrication and a better balance for applications where extreme wear resistance is not required.

Types of AR235 Steel Products

AR235 can be supplied or fabricated in different forms depending on project requirements:

AR235 Wear Plates

Used for lining equipment exposed to abrasive materials, including chutes, hoppers and material-transfer systems.

AR235 Steel Sheets

Suitable for lighter-duty applications and fabricated components requiring improved wear resistance.

Cut-to-Size AR235 Plates

Plates can be cut according to engineering drawings using suitable thermal or mechanical cutting processes.

AR235 Wear Liners

Used as replaceable liners inside equipment exposed to continuous material flow and abrasion.

Fabricated Wear Components

AR235 can be fabricated into components such as:

• Hopper liners

• Chute liners

• Conveyor components

• Wear strips

• Side plates

• Bins and bunkers

• Material-handling components

Welding 

AR235 can generally be welded using appropriate procedures. Because abrasion-resistant steels may contain alloying elements that influence hardenability, welding should be carried out according to the applicable manufacturer’s recommendations.

Important welding considerations include:

• Preheating where required

• Control of interpass temperature

• Selection of suitable consumables

• Controlled heat input

• Avoidance of excessive cooling rates

• Hydrogen control

• Proper joint preparation

For critical applications, the welding procedure should be qualified according to the applicable code or project specification.

Cutting 

AR235 plates can be cut using suitable:

• Plasma cutting

• Oxy-fuel cutting

• Laser cutting

• Mechanical cutting

Thermal cutting parameters should be controlled to minimize excessive heat-affected zones and distortion.

For thick plates or demanding applications, preheating and controlled cooling may be recommended by the manufacturer.

Machining

AR235 can be machined using suitable carbide or other wear-resistant cutting tools.

Machining considerations include:

• Appropriate cutting speed

• Controlled feed rate

• Suitable tooling

• Adequate cooling where required

• Avoidance of excessive tool wear

As hardness increases, machining becomes more demanding. AR235 is generally easier to fabricate and machine than higher-hardness grades such as AR400 and AR500.

Forming of AR235

AR235 can generally be cold formed within the limits specified by the manufacturer. Because the material is harder than conventional mild steel, forming requires appropriate equipment and tooling.

For bending operations, the following should be considered:

• Plate thickness

• Hardness

• Minimum bending radius

• Rolling direction

• Tooling capacity

• Manufacturer recommendations

Hot forming should only be performed when permitted by the applicable material specification because excessive heating may alter the steel’s hardness and wear properties.

Surface Finishes

AR235 plates can be supplied with different surface conditions depending on application requirements:

• As Rolled

• Shot Blasted

• Primed

• Pickled and Oiled, where applicable

• Cut and Machined

• Fabricated and Finished

The required surface finish should be specified during enquiry and quotation.

AR235 is widely suitable for equipment exposed to moderate to demanding abrasive conditions.

4. Good weldability when appropriate welding procedures are followed.

5. Versatile applications across mining, construction, agriculture and material handling.

6. Extended component life in abrasive operating conditions.

7. Reduced maintenance frequency when correctly selected for the service environment.

Quality and Certification

AR235 steel plates supplied for industrial applications can be provided with relevant quality documentation according to the applicable specification and purchase order.

Documentation may include:

• Mill Test Certificate (MTC)

• Chemical analysis

• Hardness test results

• Mechanical test results, where applicable

• Heat number traceability

• Dimensional inspection reports

• Material identification

• Third-party inspection documentation, when required

For critical projects, customers should specify the required inspection standard, testing requirements and certification level at the enquiry stage.

Why Choose AR235?

AR235 is a practical choice when an application requires better abrasion resistance than ordinary structural steel without moving directly to very high-hardness wear grades.

Its combination of approximately 235 HBW hardness, wear resistance, toughness and fabrication capability makes it suitable for a broad range of industrial wear applications.

The correct grade should always be selected according to the actual wear mechanism, impact level, material being handled, operating temperature, plate thickness and fabrication requirements.

Conclusion

Abrasion Resistant Steel AR235 offers a balanced combination of hardness, abrasion resistance, toughness and fabrication performance. With a nominal hardness of approximately 235 HBW, it is suitable for components exposed to moderate to demanding wear conditions.

Compared with lower-hardness wear grades such as AR200, AR235 provides improved abrasion resistance, while remaining easier to fabricate than higher-hardness grades such as AR400.

Because AR235 is used as a commercial or hardness-class designation by different manufacturers, the exact chemical composition, hardness range, mechanical properties and applicable standard should always be confirmed from the manufacturer’s specification and MTC.
