Abstract:

Materials used for the shells of pressurized railroad tank cars ; must be strong and inexpensive, yet also easily weldable and ; resistant to fracture. The high costs associated with special alloy ; compositions have made it difficult in the past to find improved ; materials that attain all of these goals. Recent advances in steel ; making research indicate that commercial grade low alloy steels ; have the potential to offer improved properties at moderate cost in ; thicknesses suitable for tank car construction, if modern ; thermomechanically controlled processing methods are applied. ; Results are presented from a heat transfer analysis of controlled ; quench schedules for 12.7 and 25.4 mm thick plate. The ; calculated cooling curves are compared with an isothermal ; transformation diagram for a medium carbon low alloy steel. The ; results suggest the possibility that interrupted water spray ; quenching might produce carbide-free bainite, a microstructure ; now associated with the combination of high strength, high ; fracture toughness, and good weldability.
