Annealing and Normalizing Treatments

To obtain states close to thermodynamic balance
Through Thermetco, we offer you a full line of annealing treatments. These treatments are dedicated to carbon steels, low alloyed steels, stainless steels and non-ferrous metals.

Types of Treatments

Full Annealing

Used to soften a material completely and improve its machinability, by creating a balanced metallurgical structure, free of internal stresses.

Soft Annealing, or Machinability Improvement

To soften a metal or a hardened alloy by a previous fabrication process.

Homogenization Annealing

To obtain both a homogeneous chemical composition and softening of the material, by heating and prolonged retention at high temperature.

Normalizing

This treatment, like full annealing, results in ferrite-perlite structures and very homogeneous microstructures. They are often sought in certain mechanical applications and constitute an ideal state for quenching.

Tempering

Treatment performed at low temperature after quenching to eliminate brittleness and stresses and adjust the final hardness.

Spheroidizing

Increases the cold working capacity of the treated metal.

Stress Relieving

Treatment strongly recommended to eliminate the thermomechanical stresses induced by welding or hot or cold forming, prejudicial to the performance of metal parts or assemblies.
