Engineering materials

Iron and the large family of iron alloys known as ferrous metals are the most common among the engineering materials.

All commercial forms of iron are carbon-iron alloys. In fact, their distinctive features depend largely on the amount of carbon rather than on all other alloying elements taken together. Thus, if iron-carbon alloy contains less than 0.005 % carbon, it is known as pure iron. Pure iron is so soft and weak that it cannot be used as engineering material except electromagnets. Mixing iron with other alloying elements va­ries the strength and quality of iron. Thus, the classification of iron is based on the amount of carbon in it. Cast iron con­tains 4.0 to 2.0 % carbon, high-carbon steels between 2.0 and 0.5 % carbon, medium-carbon steels between 0.5 and 0.2 per cent, low-carbon steel below 0.2 per cent. Wrought iron which contains 0.06 per cent of car­bon differs greatly in that it has a large amount of slag inclusions.

Carbon is the main strengthening or hardening element in steel. But very much carbon makes steel brittle, its content, therefore, should be limited: 0.20 - 0.25 % carbon provides the best machinability.

Carbon steels can be either cast to shapes or wrought into mill forms from which finished parts are produced. There are literally thousands of steel products which surround us. Our automobiles, tools and buildings all rely on steel for their manufacture.

Engineers have to know the best and most economical materials to use. Engineers must also understand the properties of these materials and how they can be worked. There are two kinds of materials used in engineering – metals and non-metals. We can divide metals into ferrous and non-ferrous metals. The former contain iron and the latter do not contain iron. Cast iron and steel, which are both alloys, or mixtures of iron and carbon, are the two most important ferrous metals. Steel contains a smaller proportion of carbon than cast iron contains. Certain elements can improve the properties of steel and are therefore added to it. For example, chromium may be included to resist corrosion and tungsten to increase hardness. Aluminium, copper, and the alloys, bronze and brass, are common non-ferrous metals.
