Tempering (Metallurgy) | Cast Iron | Steel

In grey cast iron, the carbon is mainly in the form of graphite but, in white cast-iron, the carbon is usually in the form of cementite. Grey cast-iron consists mainly of the microstructure called pearlite, mixed with graphite and sometimes ferrite. Grey cast-iron is usually used as-cast, with its properties being determined by its composition.

metallurgy - Students | Britannica Kids | Homework Help

Molten metal may be cast, or poured into simple molds, for further working. Molten iron is poured into molds to make bars of pig iron. Sometimes metal is poured into a single cast and shaped to its final form. Although this method is cheaper, it results in a lower-quality product.
