Our stainless precision steel strip with an austenitic microstructure in an annealed finish is characterized by excellent corrosion resistance combined with exceptional forming properties. In the case of the cold-worked versions, the focus is not only on corrosion resistance but also, in particular, on tensile strength, where we achieve values of up to 2,200 MPa and more.
Austenitic stainless steel strip in annealed or cold rolled versions
Thanks to specially designed rolling and annealing processes that complement each other perfectly, we can create an extremely homogeneous austenitic microstructure that is specifically optimized for formability. Our stainless precision steel strip with an austenitic microstructure is therefore the first choice when it comes to combining corrosion resistance and excellent formability – such as for deep drawing and stretch forming processes. The high isotropy with low earing also ensures direction-independent forming behavior and uniform flow during deep drawing and stretch forming – the best prerequisites for the production of components that require high degrees of deformation.
High toughness and excellent ductility of austenitic cold rolled steel strip
One special property of stainless steel with an austenitic microstructure – high plasticity – is particularly advantageous in forming processes with tight radii or when using very thin material. The material remains highly ductile even at extremely low temperatures, which is important for cryogenic applications such as liquid gas pipes or components used in satellites that are sent to space.
High-precision cut edges
Thanks to state-of-the-art process control, we can customize our austenitic stainless steels to have precisely defined cut edges. In addition to the shape of the edge, this includes minimizing burr formation. A uniform cut edge is essential for precise joining, for example in the production of precision tubes. In combination with the material’s excellent weldability, this makes it possible to achieve exactly symmetrical weld seams.
Hard-rolled with high tensile strengths of up to 2,200 MPa
We also offer stainless precision steel strip with an austenitic microstructure in hard-rolled versions, in which the cold working process achieves an extremely high level of tensile strength. With the help of finely calibrated alloy variations and specially parameterized rolling processes, we can customize the strength and elongation values to meet individual customer requirements. This is how we maximize the benefits offered by the material properties for our customers.

Stainless spring steel strip according to DIN ISO 10151
Spring steel strip is used for components designed to be deformed by building up tension in the end product and then, after the tension has been released, to return elastically to their original state without permanent deformation. Our stainless spring steels with an austenitic microstructure offer the combination of high tensile strength and high elasticity. By using materials with a high degree of purity, we also ensure that cracks do not form on the surface of the material when molding tight radii.
Benefits of stainless spring steels
- High tensile strength
- High ultimate strain
- Thickness range from 0.05 – 2.00 mm (0.002 to 0.0079 inch)
- Excellent flatness (after stretch-bending)
- Material properties that remain constant over the entire strip length
- Meets high demands on the purity of the material (no material inclusions)
