Ferrite
Our ferritic chromium steels exhibit excellent corrosion resistance and, in the spheroidize-annealed versions, stand out thanks to outstanding forming properties. This is due, among other reasons, to their highly homogeneous microstructure, in which the grain size can be precisely adapted by us to suit the desired forming operation. Furthermore, we can customize the surface topography of the material to match the lubricant used during further processing.
Stainless cold rolled steel strip with an exceptionally wide thickness range
One distinctive feature of our range of materials is that we offer ferritic stainless steels in thicknesses from 0.05 to 4 mm (0.002 – 0.157 inch). This means that we go well beyond the thickness ranges typically available. This is possible thanks to our extensive array of cutting-edge production lines.
Version rolled to achieve high tensile strength
While it is not possible to harden ferritic stainless steels martensitically (see martensitic stainless steels), it is possible to increase their tensile strength through cold working. If the material is rolled to specifically increase tensile strength (2H), we can achieve significantly higher tensile strengths of over 1,000 MPa compared to standard materials. As a result, our +C1000 strength class far exceeds the maximum standard +C850 strength class as per DIN EN 10151.
