AISI8260/21NiCrMo2/DIN1.6523 high-quality hot forged steel shaft
for mechnical purpose, OD: 80-1200mm
APPLICATIONS:
AISI 8620 is a common, carburizing alloy steel used for a variety
of medium-strength applications including gears, camshafts,
fasteners, and chains/chain pins. Flexibility in hardening
treatments allow optimization of case/core properties. Typical uses
are: Arbors, Bearings, Bushings, Cam Shafts, Differential Pinions,
Guide Pins, King Pins, Pistons Pins, Splined Shafts, Ratchets,
Sleeves etc..
