However, it was found for sintered steels that MoS2 reacts with Fe during sintering at temperatures above 600 °C, forming Fe1-xS sulfides , which compromises the beneficial effect of sulfur addition. The major advantages of the addition of alloying elements in tool steels balancing the additional costs can be summarizing as follows: • Higher strength • Less distortion during heat treatment 16 1 Introduction • Better abrasion and wear resistance • Higher toughness at same hardness levels • Better red hardness and strength at elevated service temperatures.
A major part of this thesis was dedicated to the fatigue investigation of AISI D2 type steel. Therefore, in the experimental part a more detailed description of this steel follows. All the steels described above can be used for cold work applications. However, since they do not resist softening at elevated temperatures they cannot be used under such service conditions. For purposes such as hot working, die casting, cutting operations, several hot work and high speed tool steel grades exist that contain significantly higher amounts of costly alloying elements that can support high red hardness of the material.
Accordingly, for a similar steel (NF 100C6) Marines et al.  observed a continuously decreasing shape of the S–N curve without any indication of a step and thus also proposed that the stepwise S–N curve rather represents the rotating bending behavior than the properties of the steel. These authors  also suggested that the specific appearance of the S–N curve originates from the stress gradient occurring in rotating bending tests. 2 Fatigue of Materials 37 Fig. 14 S–N data of JIS-SUJ2 bearing steel under: a rotating bending, b axial loading after Sakai et al.
