- Marine Propeller Shaft
- Forged Marine Shaft
- Ship Propulsion Shaft
Our ship main shaft is produced using high-quality alloy steel through a precision forging process that includes heating, pressing, heat treatment, and machining. This advanced manufacturing method ensures superior strength, durability, and dimensional accuracy, making it ideal for use in marine propulsion systems. The forging process enhances the material properties, providing excellent resistance to fatigue and corrosion in harsh marine environments.
