Cementing

Cementing is a heat treatment process used to increase the surface hardness of steel by introducing carbon into the outer layer of the part through controlled diffusion, while keeping the core tough and resilient.

At AEB Torneria, cementing is managed in collaboration with highly specialized external suppliers, selected for the reliability of their equipment and their ability to meet strict thermal standards. The treatment is an integral part of the advanced service offering that AEB coordinates to deliver high-performance components ready for use in demanding sectors such as transportation, safety, civil industry, medical, and sports.

AEB oversees the technical coordination, part preparation, and final inspection, ensuring that every stage of the process complies with customer specifications, both in terms of surface hardness and mechanical stability.

Technical features and benefits of cementing

Enhanced surface hardness
The treatment creates a hardened outer layer resistant to abrasion and wear, with a controlled depth, while keeping the core elastic and capable of withstanding shocks and bending. This extends the component’s service life while preserving its mechanical integrity.

Process control and uniform results
Through certified suppliers, AEB ensures the execution of cementing in temperature- and atmosphere-controlled furnaces with precise time and heat parameters. This guarantees a uniform hardened layer, compliance with dimensional tolerances, and minimal thermal distortion.

Resistance to fatigue and cyclic loads
Cementing significantly improves the component’s resistance to repeated stresses, vibrations, and dynamic loads, making it suitable for high mechanical stress environments, such as in gears, shafts, bushings, and other wear-exposed parts.

Typical applications of cementing

Transportation and automotive sector
Shafts, pins, gears, and moving parts that must ensure long-term surface resistance and mechanical reliability, even under high load conditions.

Safety and civil sector
Mechanical parts used in complex systems that require extended service life, dimensional stability, and performance reliability, even in aggressive environments or heavy-duty conditions.

Mechanical, medical, and sports industries
Precision components that require a balance between surface hardness and internal strength, often used in devices subject to safety, hygiene, or high-performance requirements.
