New high-strength, room-temperature-formable steels

Many of the critical elements of a vehicle’s crash structure such as the B-pillars and frame rails are often made of a high-strength steel (HSS) called press-hardened boron steel. This specialized steel grade (with 0.002% to 0.005% boron) is especially good at absorbing large amounts of impact energy and offers strength levels that allow design engineers to use thinner sections and thus save weight. more
