Abstract (en)
[origin: WO2009034282A1] The invention relates to a martensitic stainless steel characterised in that it comprises in weight percent: - 0.22% < C < 0.32% - 0.05% < N < 0.15%, with 0.33% < C+N < 0.43% - 10% = Cr = 12.4% - 0.10% = V = 0.40% - 0.10% = Mo = 1.0% - traces < Ni = 1.0% - traces < Mn < 1.0% - traces < Si < 1.0% - traces = W = 1.0% - traces < Co < 1.0% - traces = Cu = 1.0% - traces < Ti < 0.010% - traces = Nb = 0.050% - traces = Al = 0.050% - traces < S < 0.020% - traces < O < 0.0040% - traces < P < 0.03% - traces < B < 0.0050% - traces < Ca < 0.020% - traces < Se < 0.010% - traces < La < 0.040% - traces < Ce < 0.040%, the balance consisting of iron and impurities resulting from the production. The invention also relates to a method for producing a part made of such a steel and to the part thus obtained, as a mould element for the production of plastic articles.
