Profiled rolling stock and method for manufacturing the same

摘要

A profiled rolling stock, in particular a running rail or railroad track made of an iron-based alloy, is provided. The alloy contains silicon plus aluminum below 0.99 wt. % of the rolling stock. A structure in the cross section is formed, at least partially, by isothermic structural transformation due to accelerated cooling from the austenite region of the alloy to a lower intermediary phase temperature and holding. Transformation preferably occurs between the martensite transformation point of the alloy a temperature 250 DEG C. over the martensite transformation point Ms.
