Common Material Grades
Steel for the Nuclear Power Industry: 18MND5 is a typical material used to manufacture the conical cylinders of primary equipment in the nuclear island.
Petrochemical/General-Purpose Steel: Refer to high-strength, heat-resistant, or corrosion-resistant materials such as 42CrMo, 34CrNiMo6, and 304/316L stainless steel.
Dimension Range
Examples of Small to Medium Sizes: Inner diameter approximately 815–1000 mm, wall thickness 185 mm, height 1350 mm, taper approximately 11.1°.
Examples of Large/Extra-Large Sizes:
• Outer diameter 4,955 mm, inner diameter 4,240 mm, height 2,720 mm, taper of 15° on one side, forged from a 185-metric-ton steel ingot.
• The “world’s largest irregular-shaped hydrogenation cylinder forging,” with a maximum diameter of 6,760 mm, featuring a conical shape.
Characteristic Dimensions: The minimum diameter at the small end is typically no less than 3,000 mm, and the wall thickness is typically no less than 100 mm.
Major Application Areas
Nuclear Power Generation: Used to manufacture core pressure-bearing components such as transition cones for nuclear power evaporators and reactor pressure vessels.
Petrochemicals: Used to manufacture the conical cylinders of large hydrogenation reactors, which are key components of hydrocracking units.
Pressure Vessels: Used for the conical sections of various large vessels that must withstand high temperatures, high pressures, and complex loads.

Our heavy-duty forging presses support open-die forging and deformation of large-section forgings, including discs, shafts, blocks, and custom components. This capability enables us to meet the demanding forming requirements of heavy industrial applications.
Heat treatment is a critical step in achieving the mechanical properties required for heavy-duty forgings. Our process capabilities meet the strength, toughness, and structural stability requirements for forged components used under demanding operating conditions.
We offer machining capabilities for large forged shafts and long cylindrical components, supporting both rough and finish machining. This capacity is suitable for stepped shafts, rotor shafts, rollers, and other heavy-duty forged shaft components.
Our machining facilities are capable of handling large ring-shaped forgings and circular parts that require precise turning, face machining, boring, and contour control. This capability is suitable for industrial ring blanks, heavy-duty circular parts, and machined ring forgings.
We offer machining solutions for heavy-duty cylindrical, hollow, and tubular forgings. This capability supports the machining of sleeves, cylinders, and other thick-walled forged components used in pressure vessels, rotating systems, and general industrial applications.
Quality control is integrated into our production process through the inspection and testing of forged and machined parts. Our capabilities help verify the dimensional accuracy, condition, and quality consistency of industrial forgings prior to delivery.
Finished forgings are properly protected and packaged to minimize the risk of damage during storage and transportation. Our packaging methods ensure the safe domestic delivery and export shipment of machined and high-value forged components.
