The invention relates to components from higher carbonaceous austenitic steel castings with TRIP 0.15 to 0.6% [...] Properties with a-carbon content of greater than /, -0.1 to 0.5% greater nitrogen content, -manganese content greater 2 to 22%, -nickel content of 0 to 4%, -chromium content greater 2 to 14%, -4% molybdenum content of 0.5 to, -aluminum content greater 0 to 2%, 0.5 to 4% silicon is greater-, -niobium content is from 0 to 2%, -tantalum content of 0 to 1%, -titanium content of 0 to 3%, -vanadium content of 0 to 1% and-a total of rare earths elements yttrium, zirconium, cerium or. Lanthanum between 0 to 0, 8%, -remainder iron and [...]steel accompanying elements, wherein the component comprises a TRIP-effect under load, so that at a deformation or. Destruction a phase transition occurs, the lead to an increase in the tensile strength, the elongation at break and identation work resulting from impact. Also the invention relates to method to their preparation and their use.
