Wearalloy 450 Plate

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.

Available Services:

Wearalloy 450 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 450 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 450 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.
