Nuclear-grade fasteners engineered for reactor internals, steam generators, and critical service hardware. Decades of thermal stability, irradiation resistance, and complete material traceability.
Nuclear fasteners operate under conditions where failure is not an option: reactor internals experience neutron irradiation, high-temperature water chemistry, and decades of continuous service. Inconel 718 provides high strength for reactor internals and control rod drive mechanisms with full lot traceability. Nimonic 80A offers long-term thermal stability for steam generator internals where decades of creep life matter more than peak strength. Inconel 625 resists primary water stress corrosion cracking in core components. Hastelloy C-276 handles waste treatment and reprocessing environments with mixed corrosive streams.
