Engineering Materials
Cobalt in steel

Improves cutting ability and reduce hardenability

Refines grain size and produces less tendency to carburisation, improve corrosion and heat resistant proper ties

Improves wear resistance, cutting ability and toughness

Gives ductility, toughness, tensile strength and anti corrosion property

Engineering Materials
Malleable cast iron

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

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

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

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
