Nitriding Characteristic of Two New Steel Grades for Demanding Transmission and Bearing Application

Source

This article presents the investigative work performed on two newly developed nitriding steels for demanding transmission and bearing applications. The experimental work on both AD65N and Hybrid Steel has shown that it is possible to achieve a higher surface hardness and better residual stress profile as compared to the reference material, indicating that both materials have the potential to replace the current materials and to improve the overall property of future gears and bearings in demanding applications. The promising results enable additional characterization and rolling contact fatigue tests to be planned, which will further increase the technology readiness level for both newly developed steels.
