What is AR200 Hardness and Its Applications?

Understanding AR200 Hardness

AR200 hardness refers to a specific level of hardness in materials, particularly in rolled steel plates. The designation 'AR' stands for "Abrasion Resistant," and the number '200' indicates the hardness level measured in Brinell hardness units. Specifically, it signifies a hardness of 200 BHN (Brinell Hardness Number), which is a measure of a material's resistance to deformation when subjected to compressive loads.

Characteristics of AR200 Hardness

Materials with AR200 hardness typically exhibit high wear resistance and durability. This hardness level is achieved through a process called quenching and tempering, which enhances the material's mechanical properties. AR200 plates are often composed of alloy steels that are specifically formulated to withstand abrasive wear and impact forces.

Properties of AR200 Steel

The key properties of AR200 steel include:

• High Strength: Enhanced tensile strength and yield strength make it suitable for demanding applications.
• Wear Resistance: Exceptional ability to resist abrasion from materials such as gravel, sand, and slurry.
• Impact Resistance: Ability to withstand high-impact loads without significant deformation.

Applications of AR200 Hardness

AR200 hardness materials find extensive applications in various industries due to their toughness and wear resistance. Some of the primary applications include:

Mining and Heavy Equipment

In mining operations, AR200 plates are used in the manufacturing of equipment such as shovel buckets, wear liners, and dump truck bodies. The high wear resistance extends the lifespan of these components and minimizes downtime for repairs.

Construction Industry

AR200 steel is commonly utilized in construction for applications such as structural supports, grading and leveling machinery, and other heavy-duty equipment. Its strength and durability ensure safe operations in demanding environments.

Agriculture and Farming Equipment

In agricultural machinery, AR200 hardness is often implemented in components like plow blades, tillers, and cultivators. The hard steel resists wear from soil and other materials, allowing for efficient farming operations.

Material Handling and Conveying Systems

Conveyor systems, chutes, and hoppers used in material handling benefit from AR200 steel's durability as it can handle abrasive materials and resist impact without erosion. This application helps reduce maintenance costs and improve efficiency.

Conclusion

AR200 hardness is an essential factor in designing and selecting materials for applications requiring high wear resistance and structural integrity. From mining to agriculture, AR200 steel plays a crucial role in enhancing the performance and longevity of equipment subjected to harsh conditions. Its properties make it invaluable in applications where durability and resilience are paramount.
