    Sep 06, 2018· Steel, an alloy of iron, has small amounts of carbon added to it, and regular steel usually has 0.4% carbon. However, hypereutectoid steel refers to an alloy with about 1.5 to 2% carbon. Such high-carbon steel could be made by a method called carburization where carbon is gradually added to iron to make it steel, the study believes.

    Steels of such carbon content achieve maximum hardness more readily than steel of lower carbon content. Mechanism of Quenching: Quenching is an operation whereby the surface of the work piece is cooled, thus, establishing a temperature gradient within the workpiece, which in turn allows heat to flow from the workpiece to the quenching medium.

  • Heating of Steel: Oxidation and Decarburisation | Metallurgy

    It is a process of selective (preferential) oxidation of the carbon in steel when heated for heat treatment. The carbon is removed from the surface layers while the iron does riot get oxidised. Thus, there is a thickness from the surface towards interior, in which, the carbon content is less than the original carbon content of the steel.
