Explanation:

This cast iron is obtained from white cast iron by heat treatment process. It is mostly obtain by annealing of white cast iron. It has improved strength and ductility like steel but can be cast easily.  It is often used for small castings requiring good tensile strength and the ability to flex without breaking (ductility). Uses include electrical fittings, hand tools, pipe fittings, washers, brackets, fence fittings etc.
