A METALLURGICAL ANALYSIS OF ELEVEN STEEL PLATES TAKEN FROM A TANK CAR ACCIDENT NEAR CALLAO, MISSOURI

A metallurgical analysis of eleven steel plate samples designed as Callao samples K-1, K-2, K-3 and K-5 to K-12 was requested by the Bureau of Railroad Safety, Federal Railroad Administration, Department of Transportation. The Callao samples were removed from a tank car numbered GATX 94451 which had been involved in an accident near Callao, Missouri where the ambient temperature was reportedly 15F. An investigation was conducted at the National Bureau of Standards to determine if the plate sample conformed with the Association of American Railroads (AAR) Specification AAR-TC128-65 (flange quality, grade B, fine-grain practice) for high-tensile strength, carbon-manganese steel plates for tank cars, and to gather information pertinent to the question of the suitability of this type of steel for use as plate materials of tank cars.
