Abstract: 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 −20° C. before the shaping and is shaped at a temperature below −20° 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 −20° C. is carried out in a thermally regulated cooling apparatus.

Abstract: A hot-shapable uncoated steel-plate workpiece is press hardened by first transporting the plate through a heating zone continuously or discontinuously and there heating the plate to an austenitizing temperature while blocking entry of oxygen into the heating zone. Then the heated plate is cooled in a cooling zone to a martensitizing temperature below the austenitizing temperature without contacting the heated plate with oxygen. Finally, immediately and without cooling of the cooled workpiece to a martensite start temperature, the cooled workpiece is deformed at least partially in a finishing press into a desired shape.

Abstract: A steel for making acid-gas resistant parts for power generation, pipes, tanks, pipelines for gases or other fluids, for parts in contact with hydrogen, bipolar plates of fuel cells and heat exchangers. The high-manganese austenitic steel. The steel has in weight percent
0.02 to 0.12% carbon,
0.05 to 0.5% nitrogen,
10 to 20% manganese,
10 to 20% chromium, and
remainder iron with usual impurities.
