Introduction to Nuclear Forgings
Nuclear power plants require components that can withstand high pressure, extreme temperature, and long-term radiation exposure. These challenges make nuclear forgings a preferred solution for pressure vessels, steam generators, reactor internals, turbine shafts, and other safety-critical parts. Unlike standard industrial forgings, nuclear-grade materials must meet strict specifications for quality, toughness, and traceability. The forging process provides uniform microstructure, high strength, and improved fatigue performance, ensuring long service life in demanding nuclear environments.
As a professional Nuclear Forgings Manufacturer, we produce forged components from certified nuclear-grade steels including SA508, SA533, 20MnMoNi55, SA182 and other materials required for nuclear pressure vessels, steam generator shells, forged rings, flanges, and heavy-wall cylindrical parts. All forgings are manufactured with process control, inspection, and documentation that meet nuclear safety and regulatory requirements.
Nuclear-Grade Materials and Manufacturing Standards
Forgings for nuclear applications require compliance with international standards such as ASME Section III, RCC-M, ASTM, EN, and customer-specific specifications. Each step of the manufacturing process—from ingot melting, open-die forging, heat treatment, machining to final inspection—is carefully monitored. The objective is to guarantee mechanical properties, corrosion resistance, and dimensional accuracy for long-term operation.
Typical nuclear-grade steel forgings include:
Reactor pressure vessel forgings
Steam generator rings and shells
Large ring forgings for containment systems
Heavy-wall pressure components
Nuclear flanges and connectors
The ability to produce large nuclear forgings and maintain metallurgical consistency is essential. This demands high-tonnage forging presses, precision heat treatment, and non-destructive testing techniques such as UT, RT, MT and PT.
