Spur gear slew drive housing select nodular cast iron QT450-10

The housing blank of the spur gear slew drive is made of casting by nodular cast iron QT450-10. Unique Transmission chooses nodular cast iron QT450-10 as the housing material of the spur gear slew drive, because the comprehensive properties of the material are very suitable.

Nodular cast iron QT450-10 is carbon in the form of spherical graphite, its mechanical properties are much higher than gray cast iron and almost close to steel. It has excellent casting performance, easy cutting, good wear resistance, impact load resistance, corrosion resistance, suitable for manufacturing high grade castings, important housings, etc.

Nodular cast iron QT450-10 executive standard: GB/T1348-2009
Mechanical properties:
· Tensile strength σb (MPa): ≥450
· Conditional yield strength σ0.2 (MPa): ≥310
· Elongation δ (%): ≥10
· Hardness: 160～210HB

Easy to process, small machining deformation, good stability, not easy to be deformed when heated after processing. Using nodular cast iron QT450-10 as the housing of the spur gear drive is very suitable. The comprehensive performance of the housing is excellent, which lays a solid foundation for the production of large load and high precision spur gear slew drive.
