This hardening treatment involves cooling the previously heated steel in a controlled manner to temperatures between 750 ° C and 1,300 ° C. Almost all steels for industrial use can be quenched. Some examples are springs, bearing, and tool steels, as well as a lot of high alloy stainless steels and cast iron alloys. Through this treatment we achieve better properties:

// High wear resistance
// Improved ductility
// Excellent Hardness
// Tensile strength

After quenching, tempering is carried out at temperatures between 200 ° C and 300 ° C in order to increase toughness and reduce brittleness of the material as well as reduce the internal stress originated.

Through this process better properties are obtained.

// Excellent Hardness
// Tensile strength
// Resilience
// High ductility

Heating the steel to a certain temperature and then cooling it slowly over a period of time is known as annealing. The purpose of annealing is to refine the grain size, providing softness and improved electrical and magnetic properties as well as improved machining.

It is performed by heating the steel about 20 ° C above its critical temperature, followed by air cooling to room temperature. The purpose of this treatment is to produce a harder and stronger steel compared to annealed steel. With this process we achieve improved machinability, grain refining and an increase in hardness.

Grinding aims to correct geometric and dimensional imperfections produced during machining or heat treating the material, in this case the bars suffer deformations and thus with grinding we seek to correct them and obtain the tolerances specified by the client.

Chamfering consists of removing burrs often produced on rim of the part to avoid an edge.
