The current paper presents the design of, and field tests with bainitic wheels adopted for arctic heavy haul operations. The tests verifies the superior rolling contact and thermal fatigue resistance of bainitic wheels as compared to “conventional” pearlitic steel wheels. Further, it was demonstrated how the inherently poor wear characteristics of bainitic materials may be counteracted by a carefully controlled manufacturing process.
