Gas Turbine Bolts & Power Generation Fasteners

High-temperature bolting for gas turbines, steam turbines, generators, and balance-of-plant equipment. Materials engineered for creep, thermal fatigue, and decades of continuous service.

Which grades hold clamp load in a gas turbine?

Power generation fasteners must hold clamping load through thousands of start-stop thermal cycles, resist creep at sustained temperature, and survive in steam, combustion gas, and cooling water. Our gas turbine bolts span Inconel 718 for the hot section (to 700°C), Nimonic 80A for blade fixings and the hottest gas-path hardware (to 815°C), A-286 for compressor and diffuser bolting, and Inconel 625 for corrosion-resistant steam and water service.

Where do these bolts actually run?

Gas Turbine Bolts

Hot-section bolting for combustion liners, transition ducts, turbine casings, and exhaust diffusers. Inconel 718 and Nimonic 80A for continuous 650-815°C operation with full creep data.

Steam Turbine Fasteners

Steam path bolting, casing studs, and valve fasteners in A-286 and Inconel 625. Resistant to steam oxidation and chloride SCC in wet steam environments.

Generator & BOP Hardware

Balance-of-plant fasteners for generators, heat exchangers, condensers, and auxiliary systems. Inconel 625 and Monel K-500 for cooling water and corrosion service.
