Engineering Materials
When steel containing less than 0.8% carbon is cooled slowly from temperatures above or within the critical range, it consists of
Is also known as chilled cast iron is obtained by cooling rapidly. It is almost unmachinable
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
Is produced by annealing process. I is soft, tough and easily machined metal
Contains 1.7 to 3.5% carbon in Free State and is obtained by the slow cooling of molten cast iron
