发明名称 UPPER TRACK PORTION AND METHOD OF OBTAINING SAME
摘要 The invention relates to a permanent way component, especially a points component like a nose (14), consisting of sections (22, 24) of different materials to be joined together, in which the sections are subjected to a joint heat treatment after being joined. In order to produce a permanent way component with great tenacity and elastic limit it is proposed that, looked at in the longitudinal direction of the rail, the track component exhibit a layer structure in such a way that a head section (24) on which a rail vehicle can run directly is bonded to a base section (22), where said head section consists of a high-tensile steel, where the bonded sections are heat-treated together in such a way that the head section has an ultimate tensile strength RM2 of between 1,700 and 2,200 N/mm<2> and/or an elastic limit RE2 of between 1,600 and 1,800 N/mm<2>.
