Abstract

The invention relates to a method for producing high-strength components from austenitic or austenitic-martensitic cast steel having TRIP/TWIP properties and having an equivalent value for the stacking fault energy of the austenite of W < 35 mJ/m2 according to the relationship, wherein initially semi-finished goods or molded parts made of cast steel are melted using traditional melting methods and cast without tight dimensional tolerance, wherein the semi-finished goods or molded parts are then cold-worked with a degree of working of 20% to nearly 100% for austenitic steels and of more than 20% to 60% for austenitic-martensitic steels, wherein the cold-worked semi-finished goods or molded parts are cooled during the cold working, and thus the heating-up of the cold-worked semi-finished goods or molded parts stops above 80 °C. The invention further relates to the components thus produced as construction elements, wear elements, or crash elements.
