The invention relates to a method for producing an ultra high strength material with high elongation by work hardening an essentially nickel-free austenitic material and then subjecting the material to heat treatment in the temperature range between 200&#xb0; C. and &#x3c;1,100&#xb0; C. within a period from 10 s to 10 minutes.

Method for producing an ultra high strength material with high elongation

The invention relates to a method for manufacturing profiled metal strips ('), in which a metal strip (&#x2032;) with predefinable material thickness consisting, in particular, of stainless steel is wound up on a coil () and guided through a rolling stand (W-W) containing several rolls (&#x2032;), wherein at least the rolls () that effectively interact with the metal strip (&#x2032;) are provided with a predefinable topography (), by means of which profiles with profile depths &#x3e;250 &#x3bc;m can be produced on both sides of the metal strip (&#x2032;) depending on the geometry of the topography () of the rolls (), and wherein the metal strip (&#x2032;) is subsequent to its profiling wound up on a coil () and, if so required, subjected to a thermal post-treatment.
