Developing Low Service Temperature Steels for Railroads Truck Castings

The research performed for the Federal Railroad Administration (FRA) previously identified six grades of steel currently used in low temperature applications that could potentially be used as truck castings. These materials are specified under the American Society of Testing Materials (ASTM) A352, Standard Specification for Steel Castings, Ferritic and Martensitic, for Pressure-Containing Parts, Suitable for Low-Temperature Service. The grades are named LCC, LC2, LC3, LC4, LC9, and CA6NM, and their most common applications are for pump and valve bodies in low temperature service.
