Increasing the price of steel scraps has increased demands for finding a new raw material for producing the ductile iron parts. In this project sponge iron was tested and results showed that mechanical properties and microstructure are acceptable in comparsion with standard conditions. For example ultimate tensile strength is more than 420 MPa, hardness 174 HB and impact energy is 12 J. microstructure included 75% ferrite and 25% pearlite. In fact with keeping on properties and structure, the price reduced to 15%.
