Cobalt Alloy Bolt

Cobalt Alloy Bolts are high-performance mechanical fasteners engineered for the most demanding thermal and corrosive environments, specifically where extreme heat or surface wear occurs. Zeron Fastners supplies bolts made from specialized Cobalt Alloys like Stellite and Haynes 25. These alloys exhibit excellent hot hardness, maintaining high tensile and creep strength at temperatures up to 1000°C. Their superior wear and erosion resistance is key to their longevity. The primary application of these Cobalt Alloy Bolts is in securing components within gas turbines, hot sections of jet engines, critical valve assemblies, and high-temperature furnace equipment.
