Description
39NiCrMo3 Round Bars / 1.6510 Round Bars
39NiCrMo3 Round Bars / 1.6510 Round Bars is a Steel with high hardening capacity and good toughness, which allows to achieve optimum mechanical properties. It is used on heavy-duty machinery parts, automotive accessories and other motor vehicles, including engine parts.
39NiCrMo3 / 1.6510 steel is hardened in oil and water, and its weldability is quite limited. Designed for heavy-duty rotary shafts, steam turbine rings, compressor parts, propeller hub, engine pump parts, steam turbine wheels, crankshaft, press parts and shafts for steam turbines.
39NiCrMo3 steel has excellent performance after heat treatment, such as hardenability, strength and toughness, and wear resistance. It is usually used for seamless mechanical tubing,and also suitable for engineering applications,such as shafts,connected rods,gear shafts and crankshafts.
39NiCrMo3 is also known as AISI 9840 / 1.6510.
AISI 9840 is defined as Cr-Ni-Mo series alloy steel as per USA standard ASTM A519. AISI 9840 steel is very similar to AISI 4340 steel, only the Ni element is lower, and the difference in other elements is almost negligible.
