Precision steel strip made of stainless steel according to DIN EN 10088, DIN ISO 9445, and DIN EN 10151

Our stainless precision steel strip with an austenitic, ferritic, or martensitic microstructure stands out thanks to precisely defined material properties that are maintained within extremely tight tolerances across numerous delivery batches. This guarantees perfect reproducibility for our customers during further processing and ensures that they can fully count on the fact that their final products will have the desired properties.

Whether corrosion resistance, acid resistance, or heat resistance – our precision steel strip made of stainless steel offers unparalleled performance. This is especially true in the case of above-average requirements for formability or later properties. Depending on the version of the stainless materials with austenitic, ferritic, or martensitic microstructures, we achieve extremely high levels of tensile strength, excellent bending uniformity, as well as outstanding formability and punchability through specially designed rolling and annealing processes that complement each other perfectly.

Our corrosion-resistant precision steel strip has been widely used for many years, particularly for demanding applications in medical technology as well as safety-related components in the automotive and electrical engineering industries. Stainless cold rolled steel strip in extremely low nominal thicknesses of 0.05 to 0.20 mm (0.002 to 0.0079 inch) is used, for example, in the production of bipolar plates for fuel cells. At the other end of the requirements scale, our advanced annealing processes also enable us to offer grades with ferritic and martensitic microstructures up to 4 mm thick, which significantly exceed general standards.

Thanks to specially designed rolling and annealing processes that complement each other perfectly, we can customize the grain size of our stainless steel grades to meet our customers’ exact requirements, while always achieving an extremely homogeneous grain structure. In addition to the highest standards of quality, we guarantee extremely consistent material properties within tight tolerances across numerous delivery batches. This ensures optimal processing properties and exact reproducibility in our customers’ production processes, which is especially important when manufacturing complex components.

We use the main alloying elements chromium and nickel to create a material that is highly resistant to corrosion, acids, and heat, thereby eliminating the need for costly and time-consuming galvanic finishing processes. Additives such as molybdenum, niobium, or titanium can be used to further optimize corrosion, acid, and heat resistance and to give the material additional technological properties such as deep-drawing, bending, or punching properties, as well as spring properties optimized for the specific application.
