Metal Fabrication


Heat treatments for annealing such as soft annealing, isothermal annealing, normalisation, distension and recrystallisation serve to soften the material to make it easier to work both with tools or through plastic deformation, homogenise its structure and reduce internal tensions.

The modified atmospheres required during this process must guarantee the condition of the metal surface, avoiding oxidation and decarburisation. For this it is possible to use mixtures based on nitrogen and hydrogen or mixtures with controlled carbon potential (SolMix® technology).

For customers in the annealing sector, SOL offers an integrated service that starts with the supply of the most suitable gases/mixtures for the specific process and the supply of plant for this stock age, distribution and mixing, through to an annealing assistance service that includes analysis of the mixture of gases in the thermal treatment ovens and specific consultancy on the process including support in the choice of the type of mixture to use on the basis of the material to be treated, the oven and the specific requirements of the customer, in addition to a chemical and metallographic analysis service.
