Abstract
A composition for steel used for tires or solid wheels of rail vehicles, which composition provides improved properties, in terms of wear, crack susceptibility, ability to withstand thermal loads, homogenous microstructural properties and suitability for high dynamic loads, as compared to standard steels used for tires or solid wheels of rail vehicles. The steel is a modification of AISI S2 steel previously only used for antifriction bearings. The elements of the composition and their presence by percentage of total mass of the steel and ratios of the presence of various elements are disclosed.
