METHOD FOR PRODUCING A COMPONENT BY HOT-FORMING A PRECURSOR PRODUCT MADE OF STEEL CONTAINING MANGANESE, AND A HOT-FORMED STEEL COMPONENT

The invention relates to a method for producing a component by hot-forming a precursor product made of a steel having a TRIP and/or TRIP/TWIP effect, having a manganese content of over 12% by weight, advantageously having up to 20% by weight and an austenite content of at least 25 to 95% by volume, advantageously at least 35 to 90% by volume, the remainder being ferrite or bainite, martensite, tempered martensite or perlite. In order to provide an improved production method which is also cost-effective and in which a higher residual formability of the component at room temperature and a significantly reduced inclination toward delayed, hydrogen-induced crack formation are achieved, according to the invention, the precursor product is formed at a hot-forming temperature above 60°C and below the Ac1-transition temperature and the original austenite content is retained in full after the forming or at least 10% of the original austenite content is retained after the forming. The invention also relates to a hot-formed component produced according to said method, and to a method for producing a steel strip as a precursor product for hot-forming a component.
