Wearalloy 400, 450, and 500 are heat treated quenched and tempered alloy steels that are used in applications where shock and abrasion are the primary cause of failure. Wearalloy 400 (388 - 430 BHN) and Wearalloy 450 (440-470 BHN) provide excellent resistance to impact and sliding abrasion. Wearalloy 500 (475 - 544 BHN) handles severe abrasion and moderate impact.
Drilling and Machining
Wearalloy 400, 450, and 500 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.
Shearing and Punching
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 and 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. Minimal cold forming can be performed on our Wearalloy 500 with proper equipment.
