carbon-chrome steel

contains l.7 to 3.5% carbon in free state and is obtained by the slow cooling of molten cast iron

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

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

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