Product Description

Product Description

DIN 39NiCrMo3 steel is low alloy steel with high hardening capacity and good toughness.It's quenching and tempering steel according to EN 10083. It could achieve optimum mechanical properties with dimensions up to approx. 80mm. Used on heavy-duty machinery parts, automotive accessories and other motor vehicles, engine parts, steam turbine rings, compressor parts, propeller hub, engine pump parts, steam turbine wheels, crankshaft, press parts and shafts for steam turbines. Buth it's weldability is quite limited.
