AUSTENITIC STAINLESS STEEL POWDER COMPOSITION WITHOUT NICKEL AND PART MADE BY SINTERING BY MEANS OF SAID POWDER

The present invention relates to an austenitic stainless steel powder with a nickel content that is less than or equal to 0.5% by weight and a specific carbon content that is greater than or equal to 0.05% and less than or equal to 0.11% by weight. It also relates to a method for manufacturing said powder by powder metallurgy, and to the part (3) resulting from the manufacturing method which has the feature of having a deoxidized layer (1) on the surface of the part (3) that extends along a thickness e that is greater than or equal to 200 [mu]m. 本发明涉及一种奥氏体不锈钢粉末，其镍含量小于或等于0.5重量％且具体碳含量大于或等于0.05重量％且小于或等于0.11重量％。本发明还涉及通过粉末冶金制造所述粉末的方法以及由该制造方法生产的零件(3)，其特征在于在零件(3)的表面上具有延伸厚度e的脱氧层(1)，e大于或等于200μm。
