Function

Ductile iron castings have been used in almost all major industrial sectors, requiring high strength, ductility, toughness, wear resistance, resistance to severe thermal and mechanical shocks, high or low temperatures, corrosion resistance and dimensional stability. In order to meet these variations in the conditions of use, there are many grades of ductile iron available, providing a wide range of mechanical properties and kinematic properties. Most ductile iron castings, as defined by ISO 1083, are mainly produced in non-alloyed state.Obviously, this range includes high-strength grades with tensile strength greater than 800 Newtons/mm and elongation of 2%. QT500-7, a general-purpose material for ductile iron manhole covers, has a Brinell hardness of 170-230HB.
