Resumen:
This document specifies flat bottom Vignole railway rails from 27 kg/m to, but excluding 46 kg/m. Eight pearlitic steel grades are specified covering a rail hardness range of 200 HBW to 440 HBW and include non-heat-treated non-alloy steels, non-heat-treated alloy steels, heat-treated non-alloy steels and heat-treated alloy steels. There are 15 rail profiles specified in this document, but these may not be available in all steel grades.
