Abstract (en)

[origin: EP0593000A1] The properties of ordinary steel for rails, check rails and rolling railway material can be improved by small quantities of tellurium. This applies in particular to the wear resistance and to the mechanical properties in the transverse direction and at oxygen contents below 0.0015 % and sulphur contents of up to 0.007 %. <IMAGE>
