DATA DISPLAY REPORT ON RESULTS OF TESTS ON MILL PLATE SAMPLES AND SAMPLES REMOVED FROM TANK CARS INVOLVED IN ACCIDENTS. PHASE 03 REPORT

One of the primary objectives of the Phase 03 "Material Study" was to assemble, through tests, the physical, chemical and metallurgical properties of: (1) Steels currently used in tank car fabrication (mill plate samples); (2) Steel samples removed from tank cars involved in accidents. To accomplish Item 1, steel samples were obtained from several of the tank car companies sponsoring the RPI-AAR Project. These samples included both shell and head plate steels and reflected various conditions of heat treatment. Steels rolled in both domestic and foreign mills were included in the program. The steel producers are identified by a code letter only since the program objective is to establish data ranges for similar steels and not to isolate particular producers. Steel samples under Item 2 above were collected by the AAR Research Center prior to the formation of the RPI-AAR Project (Glendora, Miss.; Troup, Texas; Lehigh, Kansas) and by the RPI-AAR Project team from accidents which occurred since that time (Crescent City, Ill.; South Byron, N.Y.; Callao, Mo.; Kamloops, B.C.; Houston, Texas). Metallurgical reports have been previously issued by the Project based on examination of samples from Crescent City and South Byron. The purpose of this report is to simply display all test data in tabular and graphical form in order to make it immediately available. Analysis of results, conclusions and possible recommendations will be made in the final Phase 03 report and in the Overall Project Report. This report is organized as follows: Tables 1 through 10 list all the steel samples tested and tabulate their properties and the primary results of the tests. Figures A through K shown the location of the steel samples removed from cars involved in accidents and show their relationship to the fracutre patterns in the tank plates. Finally, the results of all the Charpy V-Notch tests are given in Figures 1 through 43, the Dynamic Tear Tests in Figures 44 through 84, and the Drop Weight Tear Tests in Figures 85 through 93.
