Why TB/T 2344 60kg rail was updated to 60N railway steel rail?

Chinese TB/T 2344 standard 60kg rail is widely used for Chinese express railway rail that running speed over 350 km/h, after long term using, the technicist found that the both edge of rail head always be abrased after one year, 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). Hardness can be 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.
