General Product Description

AR400F is a through-hardened, abrasion-resistant plate with a nominal hardness of 400 HBW. This product is intended for applications where a good combination of abrasion resistance, formability, and weldability is desired. AR400F is supplied in the quenched and tempered or as-quenched condition.

Applications

AR400F abrasion-resistant plate is used in equipment subjected to abrasive wear. Some potential applications for AR400F include truck beds, buckets, hoppers, chutes, crushers, conveyor troughs, bulldozers, excavators, and concrete mixer drums.

Formability properties

The minimum recommended punch radius, R, and die-opening width, W, for plate thickness, t, for cold forming AR400F are provided in the following table. Shear burrs and heat-affected zones of thermal cut edges on or near the bend axis as well as sharp corners on edges and on gas cut or punched holes located on or adjacent to the bend axis should be removed by grinding prior cold forming.
