Abstract
A Nickel free high manganese YW35 steel which has high strength and high tenacity at low temperature, and a fishplate made of the same. The YW35 steel for steel rail fishplate is produced by adding a selected amount of Molybdenum and microelement Vanadium and Niobium in a high Manganese steel and reducing the carbon content thereof, to thereby improve the low temperature property of the steel. The YW35 steel has (by weight percentage): C: 0.32˜0.40, MN: 1.10˜1.30, Is: 0.30˜0.50, p: <0.035, S: <0.035, MO: 0.15˜0.25, V: 0.06˜0.20, NB: 0.04˜0.07, Cu: <0.20, and a balancing amount of Fe.
