Sonitherm has been active in the heat treatment of metals since 1999.

We specialize in hardening steel for weapons, tooling and precision mechanics. Some of our customers are also active in automotive and aerospace-related fields.

The use of molten salt baths ensures the highest quality in terms of heat treatment homogeneity and repeatability. Our processes also ensure reduced deformation.

Our strengths are the quality of our work, our flexibility and the speed of our treatments (from 24h to 48h except for treatments carried out externally (1 to 2 weeks)).

With its many years of experience, Sonitherm can also advise and guide you in the choice of steels and treatments best suited to your applications or your customers’ requirements.

Avec notre réseau de partenaires, nous pouvons également vous proposer des traitements complémentaires tels que : la nitruration gazeuse ou ionique (plasma), la cémentation, la carbonitruration, la nitrocarburation, la trempe superficielle par induction (délais de 1 à 2 semaines)
