Campi di applicazione di 18NiCrMo5 hot-rolled annealed round
18NiCrMo5 steel in hot-rolled round bars stands out for its high nickel content and calibrated presence of chromium and molybdenum. This composition ensures an excellent combination of surface hardness and core toughness after heat treatments.
The material is particularly suitable for the production of components subjected to severe mechanical stresses such as gears, transmission shafts and components for the automotive sector. The presence of molybdenum improves fatigue resistance and hardenability.
The structure obtained from rolling, combined with the annealed condition, ensures excellent machinability and a uniform response to heat treatments. The high mechanical strength makes it ideal for critical applications.
