| 摘要 |
The invention relates to a rolling bearing element (2), in particular a rolling bearing ring (3, 4), said rolling bearing element being made of an austenitic steel which has a composition of 16 - 21 mass percent chromium, 16 - 21 mass percent manganese, 0.5 to 2.0 mass percent molybdenum, a total of 0.8 to 1.1 mass percent carbon and nitrogen, wherein the ratio of carbon to nitrogen is 0.5 to 1.1, up to 2.5 mass percent melting-related impurities, and a remaining mass percent of iron. The sum of all the components equals 100 mass percent, and the rolling bearing element has a surface layer (6) which is produced by means of at least one measure for diffusing carbon and/or nitrogen into regions near the surface of the rolling bearing element and which contains carbon and/or nitrogen. |
