Main Shaft Steel Forging

Shaft forgings (mechanical components) Shaft forgings are cylindrical objects that are worn in the middle of the bearing or in the middle of the wheel or in the middle of the gear, but a few are square. A shaft is a mechanical part that supports a rotating part and rotates therewith to transmit motion, torque or bending moments. Generally, it is a metal rod shape, and each segment can have a different diameter.     Product Description Main shaft steel forgings are critical rotating elements that connect prime movers to driven equipment in wind, marine, power and industrial drives. Forging begins with vacuum-degassed alloy or carbon steel billets (42CrMo4, 34CrNiMo6, 18CrNiMo7-6, SA 266 Gr. 2–4) which are upset, stretched and rolled into solid or hollow shafts 150–2 200 mm Ø, ≤ 23 m long, ≤ 50 t weight. Open-die or cross-rolling achieves ≥ 4:1 reduction, eliminating porosity and aligning grain flow along the shaft axis.   Performance Quench-temper or normalise yields 450–750 MPa yie…
