It is an industrial process used to modify the physical properties of a material.
In the case of MetalCast the heat treatments are applied to metal products.
Basically a heat treatment is applied using extreme heating and cooling temperatures, in order to obtain a metallic material with the adequate hardness for its mechanical performance.
These are some heat treatments that MetalCast has:
Heat treatment that alters the structure of the metals, reducing the hardness and increasing the ductility, improving the formability conditions of the pieces.
It is necessary to heat the material above the recrystallization temperature, and keep it for a certain time. Subsequently, the material must be cooled down in a controlled process.
Technique used to give uniformity in the grain size and structure of a steel piece.
The term is used because the metal is brought to an austenizing temperature and then left to cool freely in the air.
With the standardized one, a harder and more resistant material is obtained, but not as ductile as the one obtained with a total annealing.
During aging, the precipitated elements of the alloy will be solubilized in the metal microstructure, these dissolved particles generate an intermetallic phase of reinforcement, increasing the strength properties of the alloys. Aluminum alloys of 60xx and 70xx grade are subjected to aging
Treatment process through which the steel piece obtains the maximum hardness. This is done by heating the part to the austenite phase, and then rapidly cooling it to room temperature.
The chemical composition of the metal has a significant influence on the hardening results, so various cooling methods are used; blowing air, oils, polymers, water or nitrogen. Stainless steels must be hardened from high temperatures, this makes them even more resistant to corrosion and machinable.
After hardening the martensite obtained is fragile, so the tempering treatment must be applied. It consists of heating the steel below the critical temperature (400 to 600 degrees centigrade) depending on the desired results in; hardness, tensile strength, ductility and yield strength.
