Heat treatment

To obtain certain properties, the metal is additionally processed, in particular, heat treatment is carried out. Heat treatment of metal is used either as an intermediate stage before rolling, or to complete the technological process in order to provide a given level of strength, flexibility, hardness and other properties of the product. Our company “A-Synthesis” is ready to betray certain properties of a metal or a finished product, you just need to call us by phone for more detailed information.

Today, there are a large number of different methods of heat treatment, each of which allows you to add certain properties to the metal. Among the main ones worth noting are:

• hardening;
• vacation;
• annealing;
• cementation;
• nitriding;
• aging.

The most popular methods of heat treatment over a long period of time are: annealing, tempering and hardening.

Hardening is a type of heat treatment of metals and alloys, in which heating occurs above the critical temperature, accompanied by a change in the structure of the crystal lattice of the metal, followed by a sharp cooling in one of the media: water or oil. This method of heat treatment is used when it is necessary to increase the hardness of the surface layer of the product. It should be understood that with increasing hardness, ductility decreases and brittleness increases.

Vacation – This is a metal heat treatment service that is the reverse of the hardening process. During this procedure, the hardness and strength of the metal is reduced, but flexibility is increased. Tempering is often carried out after hardening to reduce the brittleness of the metal. The procedure is carried out slowly: the metal is heated to 150-650 degrees Celsius, after which it slowly cools in air.

Annealing – it is a heat treatment procedure during which the hardness level of the metal is reduced to improve machinability, correcting the structure, improving the structure of cast steel and eliminating internal stresses. Annealing is carried out by heating the metal above critical temperatures, followed by smooth cooling in air.

The price of metal heat treatment largely depends on what properties the metal or product should have, which determines the type of work performed, and also affects pricing:

• steel grade or metal type;
• scope of work;
• the shape and size of the product.
