EVALUATION OF STANDARD AND FRACTURE TOUGH BRITISH RAIL STEELS
The properties of two fracture tough and standard British rail steels are compared to the properties of AREA rail steels. The nil- ductility transition temperature of the fracture tough steels was found to be in the range 5F (-15C) with fracture toughness values 1.5 to 2.5 times as high as that determined for the AREA steel. The fracture tough grades display a good resistance to shelling under rolling load testing. The lower hardness and tensile properties of the British steels suggest that the AREA steel should have a greater resistance to wear.
