What are Nickel Alloy Bolts?
Nickel alloy bolts are high-performance fasteners that have been produced using nickel-based materials in order to provide high strength and durability. They are applied specifically in the areas where the traditional steel bolts cannot work, especially in the high-temperature and highly corrosive conditions. These bolts are very resistant to oxidation, caustic alkali, acids and media that contain chlorides and thus guarantee long service lives in harsh environments.
Nickel 200/201, Monel, Inconel, and Hastelloy are some of the most common grades, each having its purpose in industry. Nickel alloy bolts are highly used in chemical processing plants, marine engineering, aerospace parts, refineries, and power generation systems because they have excellent mechanical stability. They are reliable in the extreme temperature and pressure fastening solution due to their performance in harsh conditions.
