Properties
Ductile iron castings are used in almost all major industrial sectors, which require high strength, plasticity, toughness, wear resistance, resistance to severe thermal and mechanical shock, high or low temperature resistance, corrosion resistance and dimensional stability. In order to meet these changes in service conditions, ductile iron is available in many grades, providing a wide range of mechanical and physical properties.
Most ductile iron castings, as specified by the International Organization for Standardization ISO1083, are mainly produced in an unalloyed state. Obviously, this range includes high-strength grades with tensile strength greater than 800 Newtons per millimeter and elongation of 2%. At the other extreme are high-ductility grades with elongation greater than 17% and correspondingly lower strength (minimum 370 Newtons per millimeter). Strength and elongation are not the only basis for the designer to choose a material, but other decisive and important properties include yield strength, elastic modulus, wear and fatigue strength, hardness and impact properties. In addition, corrosion and oxidation resistance and electromagnetic properties may be critical to the designer.
