Bainitically hardened and tempered PT-strip
Locking springs for automotive applications
Locking springs used in car seats prevent the seat backs from tilting. The challenge is that soft materials that are subsequently piece-hardened do not achieve the necessary tolerances. Pre-hardened strip from Waelzholz, on the other hand, offers excellent formability with a strength of up to 1,500 MPa, eliminating the need for piece hardening.
