Overview
Popular abrasion resistant steel grade that combines through-hardness with good levels of ductility and formability.
Surface hardness of 360-440 BHN.
Ideal for moderate-to-heavy wear uses, such as in bucket components, dump body trucks and construction equipment.
Also referred to as AR400F (formable).
