PROBLEM TO BE SOLVED: To produce steel for a rim or an integrted wheel of the railway rolling stock bringing improved solutions to wear, a tendency to cracking, thermal load capacity, uniform structural characteristics and characteristics to a high dynamic load. SOLUTION: For the rim or integrated wheel of the railway rolling stock, to steel standardized for the railway rolling stock, an improved chemical composition of the steel capable of attaining improved values as to wear, a dendency to cracking, thermal load capacity, uniform structural characterisitcs and characteristics to a high dynamic load is provided. The same is attained by utilizing special rolling bearing steel. |
