  • Publication number: 20120241053
    Abstract: In an intermediate piece for connecting molded articles of manganese steel with carbon steel, in particular austenitic manganese steel casting frogs with standard rails, the intermediate piece is comprised of steel from the group of austenitic-ferritic duplex steels having a ferrite portion of <60 wt %. The method for connecting austenitic manganese steel castings with standard rails is characterized in that an austenitic-ferritic intermediate piece made of duplex steel comprising <60% ferrite is welded with the manganese steel casting and the standard rail.

  • Patent number: 5342457
    Abstract: In a method for the production of a switch diamond for switch rails and double crossovers with a switch diamond point out of carbon steel and connector rails, the switch diamond point is rolled and submitted to heat treatment, by which the switch diamond point is transformed over its total cross-section into a fine pearlite texture, whereby subsequently the switch diamond point is tempered and at least in the area where the wheels roll over, a material removing treatment for the removal of the wheel zone texture different from the fine pearlite texture is put underneath and afterwards the switch diamond point is welded to connector rails, so that the production of a switch diamond is simplified and heat treatment in a conventional apparatus is made possible.

  • Patent number: 5170932
    Abstract: In a method for connection of railway point components (1) such as, for example, frogs consisting of austenitic cast hard manganese steel, or manganese steel rails, to rails (2) made from carbon steel, with the utilization of an intermediate piece (3) made from low-carbon austenitic steel, in which method the intermediate piece (3) is first-of-all welded to the standard rail or connecting rail (2), following which, after cutting off the intermediate piece (3) to a length of less than 25 millimeters, in a second welding operation, the intermediate piece (3) is welded to the component (1) consisting of cast hard manganese steel or to the manganese steel rail (1), an intermediate piece (3) consisting of a low-carbon, austenitic, steel, in particular a chromium-nickel-steel, stabilized with niobium and/or titanium, is utilized and, following the first welding operation, a heat treatment, in particular a diffusion-solution at a temperature between 350.degree. C. and 1000.degree. C., is carried out.
