specialized steel. Although previous international documents considered many different kinds of steels for manufacturing of railway axles, in the last few years European production concentrated mainly on two kind of steel, A1N and A4T (both defined in fiches UIC 811-1 and hereafter described). Maximum joint expansion gap A railway track blogMar 04, 2016 · A rail joint is a track component that connects two pieces of rail and it provides room for rail expansion and contraction due to the changes in temperature. The mechanical rail joint is designed to allow a gap variation and, as such, has two well defined limits of this gap. The minimum gap of a mechanical rail RAIL - JFERAIL 1803R(1703) JTR Printed in Japan Notice While every effort has been made to ensure the accuracy of the information contained within this publication, the use of the information is at the readers risk and no warranty is implied or eed by JFE Steel Corporation with respect to the use of information contained herein.
on lines carrying rail traffic which is heavier or lighter than normal rail traffic. When multiplied by the factor , the loads are called "classified vertical loads". This factor shall be one of the following:0,75 - 0,83 - 0,91 - 1,00 - 1,10 - 1,21 - 1,33 1,46. The value 1,33 Rail Sections - Wabtecrail identification, as shown below. EXAMPLE:In the figure shown the markings indicate the following:WEIGHT - The rail is 115 lbs. per yard SECTION - RE indicated 25 rail METHOD OF HYDROGEN ELIMINATION - CC indicates Control Cooled rail MILL BRAND - Rail was rolled by Bethlehem Steel YEAR - Rolled in 1991 MONTH - Three vertical slashes indicate Rail Steels ::Total Materia ArticleRail steel is extremely tough. As figure 2, rail steel resists breakage even after the yield point is exceeded. In addition, rail steel has satisfactory amount of ductility and after re-heating, can be used to complete most forming operations. Their average yield point is greater than 60,000 PSI, while actual tensile strength normally ranges
