The precious metals sector requires extremely precise heat treatment to ensure perfect ductility, surface integrity, and workability of materials such as gold and platinum alloys.

During manufacturing, intermediate annealing steps are essential to reshape the metal without defects.

Codere’s System 340 annealing furnaces are highly valued by refining houses and precious metal manufacturers. They enable controlled heating below the alloy’s melting point, followed by rapid quenching to restore ductility and facilitate forming or shaping operations.

The tooling industry is the backbone of modern manufacturing by providing precision tools.

Such as cutting instruments, dies, molds, punches, and forming tools to sectors including automotive, aerospace, medical devices, and energy. These tools operate under extreme mechanical loads, friction, and thermal cycles, requiring exceptional hardness, wear resistance, and dimensional stability.

For tool manufacturers, the success of each tool — and the quality of the parts it produces — depends directly on the precision and reliability of its heat treatment. Codere SA delivers systems that ensure repeatable, controlled, and distortion-free results for high-performance tool steels.

The medical sector requires exceptionally high precision, repeatability, and cleanliness.

Medical instruments and implants must meet strict regulatory requirements, including the ISO 13485 quality management system, and guarantee absolute reliability throughout their lifecycle.

Codere SA offers heat treatment equipment specifically designed to support these requirements. With our HTView supervision software, full traceability, advanced data recording, and remote-control functionalities are ensured—matching the stringent expectations of medical device manufacturers.

Hardening is a heat treatment process that consists of heating steel components to the appropriate temperature to form austenite, followed by rapid cooling in a quenching medium. 

During quenching (gas, salt, oil or water), the austenitic structure transforms into martensite or bainitic, significantly increasing hardness and mechanical strength.

Hardness after quenching depends primarily on the carbon content of the steel, as well as the quenching speed and atmosphere conditions. Neutral hardening is typically performed under precisely controlled protective atmospheres to ensure clean component surfaces and consistent metallurgical properties.

Carburizing is a thermochemical process that enriches the steel surface with carbon to improve hardness, strength and wear resistance. 

Parts are heated above the AC3 temperature in a controlled carburizing atmosphere and maintained for a defined time to achieve the desired case depth.

Carbonitriding is a related process in which both carbon and nitrogen diffuse into the surface. Nitrogen is typically supplied by ammonia, increasing hardenability, heat resistance and wear performance.
After carburizing or carbonitriding, parts are quenched (gas, salt, oil or water) to harden both surface and core. The higher carbon content at the surface improves achievable hardness and increases mechanical resistance.

Nitriding is a thermochemical treatment in which nitrogen diffuses into the surface of steel to increase hardness, wear resistance and fatigue strength.

Nitrocarburizing is a related process that introduces both nitrogen and carbon into the surface by adding propane or methane. 

The Nitrding treatment depth is time- and temperature-dependent, and the process is carried out under a controlled atmosphere. Specific nitriding steels allow the formation of hard nitrides (ε, γ’).

The nitriding process typically produces a two-layer structure: a compound layer and a diffusion layer, whose formation depends on the nitriding potential.

Nitrocarburizing reduces cycle time and allows greater control of layer composition.
Temperature for nitriding processes generally ranges from 490 °C to 560 °C, depending on material and desired layer characteristics.

Tempering is performed after hardening to balance hardness and toughness in steel components. 

Because hardened parts are highly hard but brittle, tempering reduces hardness, increases ductility and stabilizes mechanical properties. Temperature control during tempering is essential to achieve the desired final performance.

The required tempering temperature depends on the steel grade and the target hardness. After tempering, the microstructure becomes tempered martensite, offering the desired compromise between mechanical strength and hardness.
Depending on alloying elements, certain steels—such as maraging steels—can even gain hardness during tempering.
