Manufacture of Wrought Steel Wheels for Passenger Cars and Locomotives
This standard covers the minimum properties of wrought steel wheels for rail passenger vehicles with class of wheels based on intended service. The standard includes requirements for wrought steel wheel manufacture, heat treatment, machining, surface treatment, quality control, and finish. Also included are recommendations for marking and stamping wheels.
Manufacturing of wheels is a craft requiring specialized equipment. The Association of American Railroads (AAR) investigates, approves and tracks performance of wheel manufacturers. Duplication of this process for passenger wheels by APTA is not presently a viable option. Therefore, this safety standard recommends purchase of wheels only from AAR approved wheel manufacturers.
