Steel Heat Treatment - Fundamental Information, The Process and Benefits Heat treatment - is the application of heat to steel in order to change its characteristic or form. The quantity of heat can be calculated by means of the hotness of the steel that is being treated. Temperature may be either chilly or warm to touch, so, the treatment process can range from very cold to very hot. The range may be from cold negative to hot plus temperature. Treatment of heat is the method of heating up to hotness or coldness, drenching at that temperature then cooling from the temperature. Steel can be classified in various manners. Carbon is the principal alloying element which influences the hardness of the steel and also its mechanical properties. It is essential to apply heat into the steel in order to enable its form and mechanical properties in undergoing transformation to permit the steel in functioning either during production or during cycle of its existing operation. Iron is considered the principal metal that composes the steel and the following are some of the features which we can immediately detect regarding the metal: it is steady at ordinary room temperature, it is heavy, it is magnetic, it possess a shining finish or bright shine and it is elastic or capable to bend or can be shaped easily. Ferrite is the condition in iron which has some natural qualities at ordinary room temperature like the size of a big grain, good ductility, low hardness and machinable.The ferrite condition subsists in particular crystalline form and exist at the lowest temperature. Therefore iron is composed of millions of minute particles of crystals like salt or sugar. The crystals are being bound together to be called the lattice structure. In the application of heat to iron, some things start to occur into the shiny fragment of steel. The oxygen in the surrounding begins to respond with the gleaming exterior of the of the iron in order to develop Iron Oxide. As the hotness increases, the response between the oxygen and the iron turn out to be more insistent and an evident product starts to form in the exterior of the iron that is called a scale. Once the steel When the steel attains an approximate hotness of 1,350x F, transformation in the composition takes place and also the phase. The phase transform from ferrite into austenite. Moreover, the crystal composition is modified from body-centered cubic into face-centered cubic.
