ahss classic

The classical steel with tensile strengths of up to 1,200 MPa and more

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.

Please find detailed information in the product data sheets for ahss classic dual-phase and ahss classic complex-phase steels.

Cold-rolled steel strip

Cold-rolled steel strip

Cold-rolled steel strips made by voestalpine shine with the best surface appearance. Our continuous production process and modern H2 annealing technology allow the manufacture of high-quality cold-rolled steel strip with narrow thickness tolerances.

Portfolio

The comprehensive steel grade program makes cold-rolled steel strip a true all-round material that can be used in applications from simple sections to complex deep-drawn parts. Cold-rolled steel strip is used in the household appliance industry (e.g. for washing machines, dishwashers, clothes dryers, refrigerators, stoves, hot-water boilers), radiator industry, automotive industry (for auto body parts in less corrosive environments), packaging industry and in the tube and section industry.
