TTT Group has extensive experience in the heat treatment of parts for the automotive sector. Processes such as continuous Quenching and Tempering, Induction Hardening, Carburizing and Carbonitriding and Nitriding are widely used for different types of parts that are assembled in cars and commercial vehicles. Many of these elements are safety parts that if they do not have the characteristics required to work for what they are designed for, serious accidents or catastrophic breakages can occur. The responsibility involved in the treatment of the parts means that TTT Group has high quality standards that it offers to the supply chain for the peace of mind of all its customers.

The parts that make up the engine and the transmissions are safety parts and very critical since they withstand high temperatures and require a lot of resistance to wear.

The most common processes to which the parts are subjected are Quenching and Tempering, Induction hardening and Carburizing and Carbonitriding. In high-performance engines, ceramic coatings for both plasma spray and HVOF are also used.

The chassis, suspension and brakes components must be consistent to give rigidity and safety to the whole unit and must also be prepared to withstand inclement weather, dirt, corrosion etc.

Typical treatments and coatings made by TTT Group for these elements are Quenching and Tempering, Induction Hardening, Nitriding, Hard Chrome Plating, etc.

Examples of treated parts are:

• Ball joint bolts
• Torsion bars
• Arms
• Shock Absorbers
• Springs
• Brake pistons
• Brake discs
• Wheel bolts
