Abstract

The invention relates to a method for producing a shaped sheet metal part from a blank or a semi finished product (1) made of a material consisting of steel having at least 60 wt.% Fe and a residual austenitic content of at least 5% wherein the blank or the semi finished product (1) is partially cooled to a temperature of less than 20 °C prior to the shaping and is shaped at a temperature below 20 °C in a shaping die (2). The problem of providing a method to produce components appropriately designed in terms of load which enables a highly technical application of low temperature shaping and is designed in a particularly simple manner is solved in that a reduction of the material temperature of the blank or the semi finished product (1) takes place in a cooling device (3) maintained at a temperature below 20 °C.
