Abstract (en)

[origin: EP0640695A1] The invention relates to a corrosion-resistant alloy to be used as a material for texturable parts which are in contact, at least in part, with the skin of living beings, in particular of humans, and do not trigger any hypersensitive reactions or allergies. For this purpose, according to the invention, an alloy is provided which essentially contains the elements, in per cent by weight carbon max. 0.10 silicon max. 1.0 manganese from 11.0 to 25.0 chromium from 10.0 to 20.0 molybdenum up to 1.0 nitrogen from 0.05 to 0.55 the remainder being iron, with the proviso that the nickel content is below 0.5%, that the material, after a solutionising treatment, has been quenched and, if appropriate, cold-worked and has an austenitic microstructure.
