Abstract
The present work presents a new austenitic high-nitrogen and nickel-free steel X13CrMnMoN18-14-3, (1.4452). The cyclic fatigue behaviour of this materials was investigated under simulated body conditions. When compared to solution annealed CrNiMo-steels, fatigue endurance limit is higher. The pitting potential in Ringer's solution was measured being 1.1 V, which is in the range of CoCr29Mo6. Hence, the austenitic high-nitrogen steel X13CrMnMoN18-14-3 may be a promising alternative to CrNi-Mo-steels due to the absence of nickel and improved mechanical and chemical properties.
