Manufacturing Technique
Application
Q&T steel bars are widely used to produce various components such as:
Bolts:
high strength stud bolt, threaded rods, wind power bolt, prestressed anchor bolts, post stressed anchor bolt, steel tie rod, tie bar, tension rod, tension bar etc.
Shafts: shaft, axle shaft, crankshaft, shaft for sleeve, linear shaft, pump shaft, rotor shaft, sensor shaft, spline shaft, drive
shaft, mandrel shaft, transmission shaft, screw rod etc.
Hydraulic components:hydraulic shafts, piston rod, flanges, gear, pin etc.
Raw materials steel bars used for CNC machines, precision CNC machines etc.
Mould: Ejector pins and Ejector rods
