High-strength steels with tensile strengths of up to 1,200 MPa and more
As a pioneer in the field of high-strength cold-forming steels, especially advanced high-strength steels (ahss), the innovative steel solutions of voestalpine make a significant contribution to lightweight automotive design. Under the name of ahss classic, we offer dual-phase and complex-phase steels with different mechanical property profiles with regard to yield strength, total elongation, suitability for deep drawing, resistance to edge cracking and bendability. The portfolio guarantees optimum high-strength steel for the economical production of complex components.
Dual-phase steels
ahss dual-phase steels are characterized by low yield strength, high work hardening and tensile strength, high uniform elongation and high fracture elongation. Their deep-drawing properties are beneficial in complex structural parts, Their balanced property profile is especially noteworthy with respect to deep-drawing properties with simultaneously reduced resistance to edge cracking.

Complex-phase steel
ahss complex-phase steels were specially developed for roll-profiling, bending and edging. With even the narrowest radii and high resistance to edge cracking, they yield best formability of punched edges. They have proven their effectiveness in large-scale serial production as sections or folded components such as stiffeners, sills and chassis components.
