Do you people know why doesn't there seem to be rust on the rail tracks, while the railway track is always in contact with air and moisture, and even if they do get rusted, then after how many years they get replaced? In today's article, we are going to discuss about this topic and know the actual reason why the railway track does not rust even after being open in sunlight, rain and humidity.
Actually, it is not at all that railway tracks do not feel rust, rust is definitely there, but the process of rusting in it is very slow, that means after so many years rust seems to start appearing. So let's now try to understand how this whole process takes place and what is the reason behind it. The reason is mainly attributed to the materials used in it. The steel used to make railway tracks is quite different than that of normal iron. The steel used in rail tracks is composed of a high quality steel alloy which has higher ability of corrosion resistance.
Actually, rail track is made from steel plus Mangalloy and its combination is also called manganese steel or Hadfield steel. It contains 12 percent manganese and about 0.8 percent to 1.2 percent carbon content along with steel, and due to this mixture, the speed of corrosion of the oxidation process of railway track becomes very slow, resulting in the track does not get rusted over the years.
