In mild steel there are negligeble alloying elements which has no effect on physical & chemical properties of MS. On the other hand due to alloying elements [ Ni & Cr ] oxidation is avoided.
Ductility is a physical property because it can be observed without a chemical change to the material. For instance, if we are working with aluminum to calculate its ductility, whatever we do to the aluminum metal in the process, it will still be aluminum metal.
