The invention relates to a method for producing a shaped sheet-metal part from a panel or a semifinished part made of a material consisting of steel with at least 60 wt. % Fe and a residual austenite content of at least 5%, in which the panel or the semifinished part is at least partially cooled to a temperature below &#x2212;20&#xb0; C. before the shaping and is shaped at a temperature below &#x2212;20&#xb0; C. in a forming tool. The object of providing a method for producing load-compliantly configured components, which on the one hand permits industrial-scale use of low-temperature forming and is configured particularly simply, is achieved by reducing the material temperature of the panel or semifinished part to below &#x2212;20&#xb0; C. is carried out in a thermally regulated cooling apparatus.

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.
