Engineering Materials
Nickel in steel

Gives ductility, toughness, tensile strength and anti-corrosion properties

Improves wear resistance, cutting ability and toughness

Refines grain size and produces less tendency to carburisation, improves corrosion and heat resistant properties

Improves cutting ability and reduces hardenability

Engineering Materials
Ductile cast iron

Is produced by annealing process. It 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

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

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