Heat treatment of steel is an important process in the production of iron alloy, which allows to improve its useful properties. Today, this procedure is used to convert the natural characteristics of the majority of metal products.

Heat treated steel

Heat treatment of steel involves sequential execution of three stages:

  1. Heat the iron alloy to the desired temperature.
  2. Shutter speed of steel for a certain time.
  3. Cooling.

What happens to the iron alloy with such a procedure?

Heat treatment consists of the following steps:

1. Annealing. This process is mainly used for casting, rolling and forging. This procedure is necessary to lower the hardness or reduce internal stresses that are generated in the welded products. In addition, annealing is used to prepare the metal structure for subsequent processing of thermal nature with the aim of improving its heterogeneity. This method includes the heat treatment of 45 steel, 45KH, 40XC, 40XH, and other grades of alloy of iron. Heat treatment of steel 45

2. Normalization. This procedure differs from the previous process, the nature of the passage of the cooling stage. The last step is carried out after the exposure details. Particular attention is paid to a predetermined temperature. In this case, the steel is obtained with minor but higher hardness. The structure of these fine products. Thus, normalization become necessary to correct the composition of the weld and to obtain the desired configuration.

3. Hardening. This step is associated with the processing of steel used for forgings, castings, stampings, and parts processed mechanically with the purpose of increasing of strength, hardness, corrosion resistance, wear resistance and other important characteristics. This process represents heat ferrous alloy to a temperature above or within the transformation. Aging steel in this termopechati, as well as the subsequent cooling is carried out, as a rule, with somewhat greater speed. This is most often used aqueous solutions of salts of NaOH, oil, and air. So, for example, heat treatment of steel 40x at this stage is carried out in the oil. Rarely details of the large size are subjected to hardening in the water with the immediate subsequent low vacation. Often the products from this brand iron alloy pass this stage due to the heating by high frequency currents. The result is a high solid surface.Heat treatment of steel 40x

4. Vacation. This procedure consists in heating the hardened steel to a certain temperature. Further, the metal passes the shutter speed and cooling. The last step is generally carried out in air.

5. Aging. This stage consists in maintaining the alloy of iron with metastable structure during a long period of time. The temperature should be below room. This procedure allows the metal structure to partially move to a more stable state by changing their mechanical and physical properties.

6. Cold processing. This step is a continuation of the quench cooling that was interrupted at room temperature. The index for the metal is not critical.

The scope of the alloy of iron

As the procedure of heat treatment of steel can significantly improve the performance of parts made from the iron alloy in various grades, she is in great demand in all industries. Is no exception mechanical engineering, aircraft building, tank building, production of concrete products. The products passed thermal treatment can be operated in high dynamic loads and vibration. In addition, apply the following iron alloys in the construction of skyscrapers, factories and bridges.
