The wear resistance of wheel steels is not affected by strain hardening under rolling/sliding conditions, while it is dominated by the pre-hardness of wheel steels.
The present paper discusses the effect of baking temperature, baking time and pre-strain on the bake hardenability of ultra low carbon bake hardening steel (ULC-BH steel).
