Heat treatment can be defined as the heating cycle at different temperatures carried out under predetermined conditions, followed by fast or slow cooling to give a metal or metal alloy (ferrous or non-ferrous alloys) those crystalline structures which give it certain mechanical and/or technological characteristics.
The effect of heat treatments on the structure of a metal alloy is an important field in the science of materials, its understanding is crucial to obtain the desired characteristics with the greatest accuracy.
The binary or ternary state diagrams of an alloy are not
enough to predict what phases will be obtained after the treatment cycle since these include the phases in equilibrium conditions as a result of long time at
What happens in heat treatments is that at certain cooling speeds you get different metastable structures that gives the material the required characteristics.
The addition of a controlled atmosphere in the furnace chamber changes the chemical composition of the surface layer of the alloy, this process is defined as thermochemical treatment.
Each department carries out a dedicated production process:
Unit 1: Steel department
Unit 2: Carpentry department
Unit 3: Non-ferrous alloys department
