STUDY OF NEW RAIL STEELS AND OF THE APPROPRIATE WELDING PROCESSES

UNTERSUCHUNG VON NEUEN SCHIENENSTAEHLEN UND HIERFUER GEEIGNETES SCHWEISSVERFAHREN

The rail metal for high-speed railways carrying heavy traffic must have an elastic limit of 60-100 km/mm2, a tensile strength of 100-150 km/mm2, a high fatigue resistance, a rail corrugation resistance and welding aptitude. In the scope of these tests, 180 materials were examined; the properties demanded were to be found in perlitic steels, bainite steels and steels with a low carbon content, but it is still necessary to seek the optimisation of these steels.
