TB/T chinois 2344 Le rail standard de 60 kg est largement utilisé pour les rails de chemin de fer express chinois qui roulent sur la vitesse supérieure 350 km/h, après une utilisation à long terme, le technicien a constaté que les deux bords de la tête de rail étaient toujours abrasés après un an, and the wheel hub also be abrased much more too. So they reduce the width of P60 rail head from 73mm to 70.8mm, the radian more near wheel hub, so as to reduce the abrasion.
Please compare the drawing as below:
If you are not used for state express railway, both of rail all be workable, sometime we have 60N rail, sometime we have P60 rail, the length can be 12m, 12.5m, 18m, 24m, 25m and 30m, even more than 100m we can produce it, but transportation is a problem.
The material has U71Mn (min 880Mpa), U75V (min 980Mpa). La dureté peut être R260, 320Cr and 350HT.
We can do the term of FOB Tianjin port or CNF to your required port, please contact us to talk the details.
If you need Chinese standard 60N high speed railway rail, please feel free to write email to us: [email protected].
