Introduction to the heat treatment of carbon steel
Heat treatment of carbon steel is a controlled heating and cooling of steel metal in order to alter the physical and mechanical properties without changing the original shape and size of the carbon steel. The physical and chemical properties of carbon steel are ductility, yield strength, impact resistance and it also includes the electrical and thermal conductivities of carbon steel, etc., Heat treatment of carbon steel is very important and useful in the manufacturing process and it also increases the product performance by increasing its strength. Heat treatment of carbon steel requires high carbon steels.

The common heat treatment processes of carbon steel
The common heat treatment processes of carbon steel are
Softening.
Hardening.
Case Hardening.
Material modification.
The brief explanation of heat treatment of carbon steel processes:
Softening: Softening is done in order to reduce the strength or hardness of the carbon steel, to remove residual stresses, improve the toughness, restore ductility and refine grain size or may change the electromagnetic properties of the steel.
Restoring ductility or removing residual stresses is an important operation when a large amount of cold working is to be done. Annealing, normalizing, austempering, martempering, tempering and spheroidizing are the softening principals.
Hardening: Hardening of steels is carried out to increase the strength and wear properties. One of the pre-requirement for hardening the carbon steel is sufficient carbon and alloy content. If there is a sufficient amount of carbon steel can be hardened directly. Otherwise the surface part has to be enriched with carbon using some diffusion hardening treatment techniques such as carburizing.
Case hardening: This process hardens only the exterior part of the carbon steel, the carbon steel is relatively hard, it has wear resistant skin but preserving a tough and ductile nature of the interior carbon steel. Carbon steels obtained by this process are moderately hard. Alloy steels which have a better hardenability. This property of carbon steel can be beneficial, because it gives the good wear characteristics to the surface but leaves the core tough.
Material modification: Heat treatment of carbon steel is usually used to modify the properties of carbon steel in addition to softening and hardening. This process modifies the behavior of the carbon steel. Example is cryogenic treatment, spring aging, etc.,
I have recently faced lot of problem while learning empirical formula definition, But thank to online resources of science which helped me to learn myself easily on net.
Applications of Heat treatment of carbon steel:
Heat treatment of carbon steel is mainly used to improve the tensile strength of the steel which increases the product performance and also reduces the stress, increases the toughness of the steel.
