High-temperature fasteners engineered for industrial furnaces, heat treatment fixtures, vacuum brazing jigs, and thermal processing equipment. Resistant to scaling, oxidation, and repeated thermal cycling.
Heat treatment fasteners live in the furnace, running continuous cycles from ambient to process temperature and back, in oxidising, carburising, or vacuum atmospheres. A-286 provides the best cost-performance balance for furnace fixtures to 650°C with excellent oxidation resistance. Nimonic 80A handles the highest-temperature jigs and radiant tube supports to 815°C where thermal stability over thousands of cycles is critical. Inconel 718 delivers structural strength for load-bearing fixture components. Inconel 625 resists both oxidation and aggressive process atmospheres in vacuum brazing and controlled-atmosphere furnaces.
