Wearalloy 400 Steel Plate

If your application requires superior resistance against impact and wear, then the AR400 steel plate is an excellent solution. As an abrasion resistant 400 steel supplier, Ford Steel provides quality steel in a variety of grades and thicknesses at a competitive price. We carry thousands of tons of Wearalloy 400 steel ready to be used in a wide variety of applications, and our team of representatives is here to find you the best steel plate option that best fits your needs. 

388-430 BHN

Wearalloy 400 is a heat treated, quenched and tempered, thru hardened alloy steel for use in impact and abrasion applications.

360-420 BHN Q&T ALLOY BARS

Wearalloy 400 Bars are hot rolled, heat treated alloy steel and designed for applications where shock and abrasion are a factor. All bars are in 20 foot stock lengths with a 360-420 Brinell hardness.

What is Wearalloy 400 Steel?

AR400, also known at Ford Steel as Wearalloy 400, is a high-carbon steel with a nominal hardness of 400 and a minimum hardness on the Brinell scale of 360 to 440. Abrasion resistant steel is created by quenching and tempering forged steel plates. Quenching occurs by bringing the steel to a high temperate, between 1,500 and 1,650F, then is quickly cooled with water. During the tempering process, the steel is re-heated again below-critical temperature from 300 to 700F then is cooled to room temperatures. The quenching process creates a crystal structure within the steel that increases the hardness, while the tempering increases the steel's overall durability. The quenching and tempering process change the grain structure to increase the toughness and formability that result in a through-hardened material.

Benefits of Wearalloy 400 Steel

The AR400 steel plate is excellent for applications that weldability and formability are a must. The steel plate is versatile, and it can be cut to fit tighter spaces. Abrasion resistant 400 steel is proven to have the best-prolonged service life where abrasion is the cause of failure. Additional benefits AR400 steel offers that include:

  • Three times the strength as mild steel
  • Low cost
  • Reduces maintenance costs
  • Wear-resistant for temperatures under 250°C
  • Through-hardness

Requirements for AR400 Steel

Our AR400 steel plates meet all flatness and thickness requirements the 50% standards that are specified in ASTM A-6. All of the mechanical properties for the abrasion resistance steel matches the ASTM A370.

Available Services:

Wearalloy 400 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 400 can be sheared or punched in thicknesses up to 1/4". Flame cutting is recommended on thicker plate and on our Wearalloy 450 and 500.

Wearalloy 400 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.
