Opis

This report presents the results of a material property test program undertaken on a Class B railcar wheel steel. This work was performed to obtain relevant fatigue data that may be used in support of a larger effort exploring the applicability of fatigue-based acceptance criteria for passenger and transit railroad wheels. Classical stress-life (S-N) curves were developed for AAR Class B railcar wheel steel with specimens removed from the tread area of an as-forged railcar wheel.
