In a large part of technological processes, there is a need to change the shape or certain properties of the material used. This can be achieved by various methods, but one of the most effective is heat treatment of the metal. Please read the information below and tell us what we can do for you?

Heat treatment of steel - what is it?

Metal heat treatment is a series of processes performed on metal materials (metals or their alloys), consisting in controlled heating, soaking and cooling. These activities are carried out taking into account parameters such as time and temperature, and the aim of the treatments is to change the physical properties and internal structure. Heat treatment makes it possible to change the characteristics of the alloy in the solid state. In some cases, heat treatment of steel also requires the use of other types of treatments (e.g. mechanical).

The methods of changing the physical properties of metals and alloys are: ordinary heat treatment, thermoplastic treatment, thermo-chemical treatment and thermal-magnetic treatment. In our business we use the first type. Ordinary machining includes processes such as:

Annealing – consists in heating the detail to a high temperature (remember that the temperature range is very wide), heating (keeping it at this temperature so that the entire object heats up evenly), and slow cooling. The aim of the treatment is to improve the plastic properties of the material.

Hardening – consists in heating the element to the desired temperature and its rapid cooling. The aim of this process is to achieve high hardness. Unfortunately, this also leads to a reduction in plasticity and extensibility.

Tempering - tempering is divided into low (150-250°C), medium (250-500°C) and high (above 500°C). The process consists in heating the detail to the assumed temperature, heating and cooling in water or oil. Tempering is carried out after hardening, thanks to which it is possible to remove the stresses of hardening. The aim is also to reduce the hardness of the material. Toughness and impact strength increase.

Quenching - applies to stainless and acid-resistant steels. The purpose of the treatment is to obtain increased corrosion resistance. As in hardening, the method consists in heating the detail to the desired temperature and cooling it quickly.

Aging - this process is subjected to a previously supersaturated metal alloy. As a result, the strength of the material improves and its hardness increases. Plasticity is reduced.
