Vedclass · Answer

(A) Railway tracks are made of manganese steel,which is an alloy of iron containing approximately $10-15\%$ manganese.This specific composition makes the steel extremely hard,tough,and resistant to wear and abrasion,which is essential for the heavy loads and constant friction experienced by railway tracks.The addition of $Mn$ increases the hardness and strength of the steel while reducing its brittleness.Therefore,the correct answer is that it is hard due to the high percentage of $Mn$.Thus,the correct option is $A$.

Manganese steel is used for making railway tracks because
