    摘要: A steel for high-strength solid wheels and tires for railroad traction vehicles and cars that is more tenacious at the strengths typical of existing steels, and that is less likely to fracture even at constant braking. The steel has a specific ratio between major, alloying and companion elements, so that the steel is of high purity and uniformity. The heat treatment ensures a structure of excellent tenacity at high strength and of special endurance.
