ASTM A514 AR200 abrasion-resistant steel plate

ASTM A514 is a standard specification for high-yield strength, quenched and tempered alloy steel plates, designed for structural applications requiring superior toughness and durability. The AR200 grade of A514 steel is specifically engineered for abrasion resistance, making it an excellent choice for moderate wear environments.

AR200 plates are distinguished by a smooth surface finish with hues of blue-grey to red, reflecting the hardened nature of the material. While not ideal for forming or precision machining due to its hardness, AR200 performs well in welding operations, allowing it to be securely joined to other components.

Key Features of ASTM A514 AR200 Steel Plate:

Moderate abrasion resistance

Quenched and tempered for surface hardness

Good weldability

Not suitable for forming or extensive machining

Common Applications of ASTM A514 AR200 Steel Plate:

AR200 steel plates are ideal for applications where surfaces are exposed to medium levels of impact, abrasion, or friction. Typical uses include:

Wear plates and liners

Cement mixer drums and blades

Hoppers and material handling chutes

Screw conveyors and auger flights

Agricultural equipment components

Extended Applications and Considerations:

Beyond its standard industrial roles, AR200 is also used in construction and mining equipment, particularly in areas requiring cost-effective wear protection without the extreme hardness of higher AR grades like AR400 or AR500.

Due to its balance of toughness and workability, AR200 is often selected in projects where wear resistance is essential, but the component also needs to be cut, welded, or replaced periodically.

For example:

In aggregate handling systems, AR200 protects structural surfaces while minimizing maintenance downtime.

In recycling plants, it is used for parts that are subject to repeated loading and unloading of bulk materials.

In agricultural machinery, it offers durability against soil abrasion and mechanical contact without compromising overall equipment flexibility.

Processing Notes:

Welding: Suitable for most conventional welding methods. Preheating may be recommended depending on thickness and ambient conditions.

Cutting: Plasma or laser cutting is preferred due to the material’s hardness.

Forming: Limited; cold forming is generally not recommended.
