voestalpine martensitic steels

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.

Martensitic steels such as CR1030Y1300T-MS (MS1300) close the gap in strength when compared to hot-formed steels. With this latest steel development, voestalpine provides a portfolio 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.

Crass-relevant component made of martensitic steel in cold forming

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.

A cool solution.

The secret of homogeneity in material properties and strip flatness lies in the special, perfectly coordinated annealing and cooling technology of voestalpine, which leads to martensitic transformation. In contrast to conventional cooling (water quenching), voestalpine uses finely adjustable gas-jet cooling.

Customer-certified

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 subsequent series deliveries also confirm the outstanding, consistent product properties of MS1300 and thus the high quality of the production technologies and processes implemented at voestalpine. The ultra-high-strength steels are available in either bright-finished or electrogalvanized condition, depending on corrosion resistance requirements.
