    You will find detailed information on JFE's

    railroad rails in this catalog, including technical

    and dimensional data. This information should

    help you select the rails best suited to your

    specific needs. JFE Rails are produced in the

    shape mill at our West Japan Works. Their high

    quality reflects the superior manufacturing

    processes and quality control systems that we

    have developed during more than nine decades

    of steelmaking.

    The rails' super-clean materials are produced

    with a combination of desulfurizing, degassing

    and continuous casting processes for improving

    contact fatigue properties. And their quality is

    assured by the rigorous controls of UST, ECT

    and other systems.

    Along with the super-clean standard carbon

    rails, our head-hardened rails, JFE-SP and JFE-

    THH, which are produced by our advanced on-

    line heat treatment technologies, enjoy

    favorable reception from worldwide heavy-haul

    customers.

    JFE rail manufacturing meets the specifications

    of JIS, AREMA, UIC, BS, GB and other

    internationally recognized standards.

    We hope this information is helpful, and we

    look forward to serving you.

    Our advanced on-line heat-treatment technologies make the head-hardened region of JFE-

    SP and JFE-THH rail thick and uniform.

    Optimal alloy designing and processing bring about the outstanding wear-resistance of

    JFE-SP and JFE-THH rail.

    JFE-SP and JFE-THH have excellent weldability in flash-butt and Thermite welding.

    JFE-SP and JFE-THH rails offer consistent quality accomplished by our super-clean

    steelmaking technology, advanced on-line heat-treatment technique and rigorous

    inspection system.

    The excellent resistance to wear and rolling contact fatigue damage of JFE-SP and JFE-

    THH rails will greatly contribute to reduce the cost of maintenance and replace.

    JFE Current Transmission Rails are assured by strict quality control of chemical

    composition during steel manufacture.

    Uniformity of steel quality is made possible by JFE's special technology for minimizing

    segregation.

  • 7/27/2019 Rail Standard1832013

    32/39

    This specification covers rails used in the transmission of

    current for electric trains(hereinater referred to as the "rails").

    The appearance of the rails shall be as follows:

    The rails shall be of uniform contour along their entire

    length and free from flaws, twists, and other defects.

    The rails cut surface shall have no evidence of pipe marksor other harmful internal defects.

    The rail ends shall be cut at right angles to the longitudinal

    direction and burrs left on the cut surface shall be removed.

    The chemical composition of the rails shall conform to the

    ladle analysis and its values to Table 1.

    The chemical analysis shall be in sccordance with JIS.

    The rail samples obtained at the rate of one from each steel

    heat shall tested for electric resistance in the manner set

    forth in the annex "Method of Determining the Electric

    Resistance of Current Transmission Rails". If the requirements

    of paragraph 2.2 have been satisfied in the test, all rails

    manufactured from the said heat shall be accepted.

    To define their material characteristics, the rails shall undergo

    for reference the mechanical test set forth in Table 3.

    Electric resistance of the rails, at 20 deg C, shall be less than

    7.2 taimes that of the same volume of international standard

    mild copper.

    follows:

    The ahapes and sectional dimensions of the rails shall

    conform to the annexed drawings, JIS E 1101"Standard

    Rails".

    The standard length of the rails shall be 15m. The following

    smaller lengths may, however, be used up to 10% of the

    entire quality ordered:

    10m, 11m, 12m, 13m, 14mThe standard weight of the rails shall be provided for in JIS

    One side of the rail web shall be embossed, as shown by

    example below, with an arrow mark for the head direction of

    ingot during rolling, a symbol for the type of rail, a symbol

    for the type of steel furnace, the name or recognized

    symbol of the manufacturer, the date of manufacture, etc.

    These must be legible as long as the rail is in use.

    The other side of the web, meanwhile, shall be stamped, as

    shown by example below, with an indicationTR, a heat

    number, a symbol for the order of rail rolled from the ingot,etc.

    The end surface of the rails shall be painted orange.
