AR450 Wear Resistant Steel Plate

Wearalloy AR450 Steel Plate

As a global leader and Wearalloy AR450 steel plate supplier, Ford Steel houses a variety of abrasion resistant plates in different sizes and thicknesses.  Wearalloy 450, or AR450, lasts four times longer than other carbon-alloy steel plates. Compared to AR400, the AR450 steel plate offers more hardness without sacrificing formability and ductility. With our highly trained team of representatives, we pride ourselves in providing excellent customer service to provide you with the best solution to your specific wear problems. Our team of experts create solutions to complex challenges and to help you avoid unnecessary downtime at a low-cost solution.

440-470 BHN

Wearalloy 450 is a heat treated, quenched and tempered, thru hardened alloy steel for use in moderate impact and sliding abrasion applications.

What is Wearalloy AR450?

Wearalloy 450 Steel, also known as AR450F or AR450, is high-carbon alloy steel composed of a variety of elements, such as boron and carbon, with a surface hardness of 420-470 Hardness Brinell. AR450 is a type of abrasion resistant steel that has a unique hardness, formability, ductility, and impact resistance. The steel plate undergoes a quenching and tempering process that subjects the steel plate to heat, submerging in water, reheating, then placed in a room temperature area dry that creates a stronger crystal structure.

Sizes Offered

As one of the leading abrasion resistant providers in the industry, Ford Steel houses an assortment of AR450 steel plates in different thicknesses. The common range of thickness for AR450 steel plates range from ⅛ inch to 4 inches and come in a variety of lengths depending on the application requirement.

  • Thickness: 1/8” thru 4”
  • Widths: 48” thru 96”
  • Lengths: 96” thru 288”

Benefits of Wearalloy AR450 Steel

Abrasion resistant 450 plate protects your equipment from corrosion, wear, and impact. The steel is superior for applications that require more durability, minimizing the lost production time because of worn-out parts. AR450 has many other benefits including:

  • Less Cost
  • Less weight without sacrificing strength
  • Extremely durable
  • High Impact resistance

Requirements of AR450 Steel

Our AR450 steel plates meet all requirements and standards for EN 10029 and EN 10051.

Available Services:

Wearalloy AR450 can be machined or drilled with high speed carbide tools at low speeds. As the hardness level of the plate increases, it is necessary to decrease the cutting speed and feed depth.

For welding Wearalloy plate, we recommend that low hydrogen electrodes be used: such as E-70XX, E-80XX , E-90XX , E-10XX , E-11XX. As conditions warrant, pre-heating is recommended on all thicknesses.

Wearalloy AR450 can be sheared or punched in thicknesses up to 1/4". Flame cutting is recommended on thicker plate and on our Wearalloy 400 and 500.

Wearalloy AR450 can be cold formed in a press brake or rolls. At sharper bends, forming should be performed with the axis of bend at right angles to the rolling direction or cross grain of the plate. Remove rough edges on plate by grinding prior to forming. It is necessary to allow for a bending radius of 3 to 5 times that of ordinary steel.

Common Industries and Applications

AR450 steel plates are used in heavy equipment manufacturing jobs that rely on it to protect the equipment from extensive wear. The steel plates should not be used in load-bearing or structural design to support extensive amounts of weight. Common industries that use AR450 steel are mining, power, aggregation, cement, pulp/paper, sand & gravel, asphalt, scrap, and slag.
