Steel EN39 / AISI 9840

39NiCrMo3 steel is a high-performance and versatile metal for the creation of mechanical parts thanks to the possibility of surface hardening. The core of the component, on the other hand, maintains an excellent tenacity, which gives it excellent mechanical performance.

  • Excellent hardenability

  • Possibility to perform nitriding treatments

  • High mechanical properties

The 39NiCrMo3 alloy has excellent mechanical properties, including excellent toughness and mechanical strength. The surface of the objects produced with this material, however, can be hardened both through a tempering and nitriding process, which create a uniform and hard layer that gives excellent resistance to wear.
