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 and producing ahss steels. 

The ultralights ahss dual-phase steels 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, 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 ultralights ahss complex-phase steels Highly convincing while maintaining the narrowest radii and low 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 become resistant to corrosion as a result of time-tested coatings such as Z, ZE, ZF or ZM.
