Steel Blanks

Open Die Forging 3Tons Stainless Steel 4000mm Hollow Shaft

This product is manufactured using open-die forging and made of stainless steel, with each piece weighing 3 tons and measuring 4000 mm in length. The component features a hollow structure. High-temperature multi-step forging improves the internal microstructure, enhancing mechanical strength and fatigue resistance. With excellent dimensional stability, it is suitable for transmission components in heavy machinery, marine propulsion systems, and energy-equipment applications.

Wall thickness, diameter, and material options (e.g., 304, 316) can be customized as required. The product supports subsequent machining processes such as turning and heat treatment. Each component undergoes ultrasonic testing and hardness inspection to ensure internal soundness and compliance with industry standards.
