The 39NiCrMo3 is suitable for
different heat treatment and shows a good cold workability. Steel with high hardening
capacity and good toughness, which allows to achieve optimum mechanical properties
with dimensions up to approx. 80mm. Used on heavy-duty machinery parts, automotive
accessories and other motor vehicles, including engine parts.
The 39NiCrMo3 steel is suited to production of highly stressed components of large cross section for aircraft, automotive and general engineering applications, such as forged propeller shafts, connecting rods, gear shafts, crankshafts and landing gear components.
