Fatigue Performance of Cost Effective Cr-Ni prealloyed PM Steel, designed to replace Fe-Ni Steels and match wrought steels

Powder Metal materials that exhibit excellent heat treated properties and achieve good fatigue performance are needed to convert wrought components & gears to the PM process as well as to offer a cost effective alternate to existing the FN-020X PM material systems. North American Höganäs successfully demonstrated the excellent heat treated properties of the new developed prealloyed Cr-Ni steel (Astaloy® CMN). The purpose of this paper is to demonstrate the dynamic properties achievable with this material compared to wrought steels and FN-020X system.
