High-strength steels with tensile strengths of up to 1,200 MPa and more

With more than 20 years of experience in the development and manufacture of advanced high-strength steels (ahss), voestalpine is your expert partner for cold-formed steels in lightweight automotive components. 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. TRIP steels with tensile strengths of up to 800 MPa and extraordinary deep-drawing properties are also included in our range of products. The portfolio guarantees optimum high-strength steel for the economical production of complex components.

Dual-phase steel

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.
