Why mild steel is preferred for the design purpose ?

It is ductile material so it provide indication to the design in the form of yielding before fracture.(Brittle material does not show yielding behavior).
Coefficient of thermal expansion of mild steel is almost equal to the coefficient of thermal expansion of concrete.
Young’s modulus of elasticity is same if both tension and compression.

 ET =Stress/Strain
EC =Compressive Stress/Strain

-steel can be easily welded and joined.
-it is easily available and have less cost compare to other material.
-it is easily recyclable.

-scrap value is good.
