Carburizing steels:
Euronorme 10084. Aciers à analyse adaptée, reproductible afin de répondre au mieux aux conditions de traitements thermo-chimiques et aux conditions d’utilisation de la pièce finale. Possibilité d’adapter l’analyse en fonction des conditions de mise en œuvre par usinage (aciers à inclusions contrôlées) ou formage.
Aciers à grains fins. Aciers à grande propreté inclusionnaire pour améliorer la tenue en fatigue ou la résistance au pitting.

Heat treatment steels (thermal + surface hardening):
Euronorm: 10083-1 – 10083-2. Steels for mechanical construction suitable for hardening.
These steels exhibit good toughness in the hardened and tempered state.
A high machinability can be achieved by optimizing the microstructure and inclusion state.
