The railway track: You must have traveled in the train many times and during this time you must have seen the train tracks. Many people like you have this question in their mind that what are railway tracks made of and why do they not rust? The railway tracks always look clean and shiny. Whereas any iron item kept in the open starts rusting and gradually becomes brittle.
While some people say that there is daily train traffic on the railway tracks, so they do not feel rust. But that not the only reason. Let us tell you what the train tracks are made of and what is the reason that they do not rust?
Why does iron rust?
You must have seen that the iron kept in the open starts rusting after some time and it gets damaged but the train tracks are always shining. Actually, when steel or steel products come in contact with oxygen and moisture, iron oxide freezes on them. This is called rusting, which is a layer of brown color. This gradually leads to the deterioration of the iron.
How to protect railway tracks from corrosion?
If it is true that the iron rusts, then the railway tracks tolerate air, water and sunshine under the open sky all the time, yet why do they not rust? Very few people know about this.
Let us tell you that special metal is used to make railway tracks, which is called manganese steel and which does not rust. Rail tracks are made of steel and manganese. The mixture of steel and manganese is called manganese steel. It contains 12% manganese and 0.8% carbon. Because of this, the tracks are not affected by oxidation and do not rust for many years.
