Stainless steel is widely used in our daily life, but its compressive strength is particularly poor in terms of its characteristics. Everyone should know that the train carries a very heavy weight, and if the rails can't bear this weight, it will have serious consequences. Trains often pass by the railway tracks, which are exposed to the sun and wind and are easily corroded. In order to make the rails longer, more durable and safer, high manganese steel is generally used in the construction of rails.
In addition, from the price point of view, stainless steel is obviously much cheaper than high manganese steel. The cost of rail made of stainless steel is lower than that of high manganese steel, but for the safety of railway transportation, high manganese steel is widely used. We can ignore the price problem, but we can't ignore the safety problem. As far as the pressure resistance of stainless steel is concerned, it can be directly eliminated.
Although steel with high manganese content is prone to oxidation and rust, railway traffic safety maintenance personnel will regularly check the rails. If it is confirmed that it can no longer be used, repair and replace it. After all, the safety of railway traffic is very important to people's lives and health. The railway department has a job called flaw detection, which is responsible for the follow-up maintenance of the railway. They must strictly check the responsible road sections every day, and report the problems as soon as possible.
