For more than 20 years, voestalpine has been developing ahss steels.
The ultralights ahss dual-phase steels are characterized by low yield strength, high work hardening and tensile strength as well as high uniform and fracture elongation. Their deep-drawing properties are beneficial in complex structural parts, and their balanced property profile is especially noteworthy with respect to deep-drawing properties with simultaneously reduced resistance to edge cracking. Hot-dip galvanized and electro-galvanized surfaces provide the highest corrosion protection, and selected grades are also available for exposed-panel applications.
The bending properties of the ultralights ahss complex-phase steels are convincing while maintaining the narrowest radii and high resistance to edge cracking, thus allowing excellent forming properties in punched edges. They have proven their effectiveness in large-scale serial production as sections or folded components such as stiffeners, sills and chassis components.
These steel grades became resistant to corrosion as a result of time-tested coatings such as GI, EG, GA or ZM.
