    摘要: The invention concerns a corrugation-free rail for track-bound vehicles. In the invention, the rail comprises a metallic material in the area of the travel and/or guide surfaces of which the stress limit or yield point is above the wheel-induced compression. Preferably, the rail in the area of the travel and/or guide surfaces is composed of a non-work-hardenable material.The preferred material composition is (by weight):______________________________________ carbon 0.2 to 0.4% chromium 13 to 18% molybdenum 0.3 to 1.5% manganese 0.5 to 1.5% silicon 0.3 to 1% remainder is iron. ______________________________________
