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.

Abstract: The present invention relates to a rail clip, an important fitting part, for the railway made of a new steel XY30 which is one of a high-manganese steel without nickel and which has high strength and high toughness even if it is used in the low-temperature circumstance.

Abstract: The present invention discloses an Nickel free high manganese steel-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 some amount of Molybdenum and the microelement Vanadium and Niobium in the high Manganese steel and reducing the carbon content thereof, to thereby improve the low temperature property of the steel, said YW35 steel comprising (by weight percentage): C: 0.32˜0.40, Mn: 1.10˜1.30, Si: 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.
