Ferrous alloys fec phase diagram the vast majority of steels are in the austenitic condition at temperatures in excess of 900 c. What is produced is a blend of aluminum alloys, often containing high amounts of copper. Ferrous metals ferrous metals include cast iron, steel, and the various steel alloys, the only difference between iron and steel is the carbon content. All metals may be classified as ferrous or nonferrous. Cast iron contains more than 2percent carbon, while steel contains less than 2 percent.
Nonferrous metals, including aluminum, nickel, lead, tin, brass, silver, and. Generally these are more costly than the ferrous metals. Nonferrous metals are those which do not contain significant quantity of iron ferrite or iron as the base metal. Austenite has a cubicclose packed crystal structure and tends to decompose into ferrite bodycentered cubic and cementite fe 3 c. In general they have lower strength, hardness, and modulus of elasticity than irons and steels.
