Abstract
The present invention relates to a method for manufacturing a complex-formed component by using austenitic steels in a multi-stage process where cold forming and heating are alternated for at least two multi-stage process steps. The material during every process step and a component produced has an austenitic microstructure with non-magnetic reversible properties.
