37MnSi5 Application:

37MnSi5 is mainly used in the manufacture in quenched state medium speed, medium load of parts under; or in the quenched and tempered state as a high-impact load and small parts, can also be used and the need for greater cross-sectional surface hardening parts. In the general machinery industry, the steel for the manufacture of transmission gears, spindles, spindle, shaft, rod, worm, electric axles, generator shaft, crankshaft, flywheel and size forgings; in turbine manufacture, is used as the operating temperature the following 400 ℃, diameter less than 250mm spindle and hub, and a variety of important impeller fastener thickness less than 170mm; in the manufacture of agricultural machinery and more to handle hoe shovel, plow House and other wear-resistant parts. Also used as a thin-walled seamless steel pipe.
