Learn about the basics of Iron Casting, types of
IronCasting, and the process of Iron Casting.
Iron castings can be referred to as products made out of
melted iron molecules. These molecules are, first, poured into mold and allowed
to cool. They are then extracted. The casting properties depend a great deal on
the foundry practice. They also depend on the cooling rate. Iron contains huge
carbon concentrations. This content facilitates melting, simplicity of casting,
and machining. Iron casting designs have a great variation owing to the
property of iron to resist shrinkage during the process of cooling. The end
product attains a great reputation for its strength and durability. Tensile
strength ranges between 20,000 psi and over 60,000 psi. The values of hardness
(without heat treatment) range between 100 and 300 BHN.
