Grey cast iron

Is also known as chilled cast iron is obtained by cooling rapidly. It is almost unmachinable

Is produced by annealing process. I is soft, tough and easily machined metal

Is produced by small additions o magnesium (or cerium) in the ladle Graphite is in nodular or spheroidal form and is well dispersed throughout the material

Contains 1.7 to 3.5% carbon in Free State and is obtained by the slow cooling of molten cast iron
