Bainitic hardening in salt baths for high-precision heat treatments in Brescia

Salt Baths: Bainitic Tempering

Bainitic hardening is a heat treatment performed on metal components to improve their mechanical properties and strength. Thanks to the use of salt baths, this technology achieves a uniform bainitic structure, minimizing the deformations typical of traditional hardening. Tecma Srl, based in Brescia, specializes in advanced heat treatments and offers dedicated bainitic hardening systems, guaranteeing certified quality and rapid processing times.

What is Bainitic Tempering and How Does It Work?

Bainitic hardening involves heating steels to a specific temperature and then cooling them in a controlled manner in a molten salt bath. This method produces a bainitic microstructure, known for its excellent mechanical properties.

The main advantages of this process include:

Speed of execution compared to other tempering methods.
Minimal deformations, even in the presence of complex geometries
Increased resistance to mechanical fatigue and wear
Possibility of working with small or very small production batches
Possibility of localized treatment of the pieces

Thanks to its versatility, bainitic hardening is particularly suitable for components intended for high mechanical stress machining.

Advantages of salt baths in bainitic tempering

The use of salt baths makes bainitic hardening an ideal solution for companies requiring dimensional accuracy and high performance.

Why choose salt baths

Salt baths ensure uniform cooling of the treated parts, reducing the risk of distortion. This allows for parts with precise dimensional tolerances, avoiding costly subsequent machining. Furthermore, the ability to perform localized treatments is an additional advantage when certain areas of the components need to be preserved.
