Best strip flatness, highest strength, excellent formability
The martensitic steels of voestalpine are characterized by excellent formability during bending and roll forming as well as by highest strength. Their property profile is perfect for lightweight automotive design and for safety and crash components in cold forming. The material and forming properties are convincing, and the remarkable strip flatness of the steel strip is an advantage appreciated by processing firms.
Excellent combination of properties
Our martensitic steels such as CR1030Y1300T-MS (MS1300) close the gap in strength when compared to hot-formed steels. We offer a portfolio of steels with minimum tensile strengths ranging from 1100 to 1300 MPa. They supplement hot-formed steels in the manufacture of safety and crash components such as side members, rocker panels, seat rails and car body components.
The extremely high resistance to edge cracking during the forming of punched edges is also important to emphasize. This is due to the single-phase martensitic structure.
Cool solution for high-end quality
The secret of homogeneity in material properties and strip flatness lies in the special, coordinated annealing and cooling technology of voestalpine, which leads to martensitic transformation. In contrast to conventional cooling (water quenching), we use finely adjustable gas-jet cooling.
Customer-certified, proven in series production
The CR1030Y1300T-MS grade has already been approved by customers, with the steel achieving particularly high scores for its uniform material properties and excellent strip flatness. The ultra-high-strength steels are available in either bright-finished or electrogalvanized condition, depending on corrosion resistance requirements.
