What’s malleable cast iron ?
Malleable iron is cast as white iron, the structure being a
metastable carbide in a pearlitic matrix. Through an annealing heat
treatment, the brittle structure as first cast is transformed into the malleable form.
What is Iron ?
Iron is a chemical element with symbol Fe (from Latin word Ferrum).
Its atomic number is 26 and atomic mass is 55.85. It has a melting
point of 1538 deg C and boiling point of 2862 deg C. The density of iron is 7.87 grams/cu cm. It is a metal in the first transition series. Like the elements
of other group 8 elements (ruthenium and osmium), iron exists in a wide range of
oxidation states,Iron as a common metal is mostly confused with other metals such as
different types of steels.
Iron is by mass the most common element on the earth, forming much
of earth’s outer and inner core. It is the fourth most common
element and the second most common metal in the earth crust. Steels
contain over 95 % Fe. Elemental iron occurs in meteoroids and other
low oxygen environments, but is reactive to oxygen and water.
Fresh iron surfaces appear lustrous silvery-gray, but oxidize in normal air to give hydrated iron oxides, commonly
known as rust. Unlike the metals which form passivating oxide
layers, iron oxides occupy more volume than the metal and thus
flake off, exposing fresh surfaces for corrosion.
