C276 Hastelloy Hex Bolts Specification
- ASTM B574
- ASME SB574
The Hastelloy C276 is the most popular and adaptable corrosion-resistant of nickel alloy, which is also quite strong. Hastelloy C276 provides excellent resistance to localized assault and substantially reduces and mildly oxidizes corrosive acids. The Hastelloy C276 bolt's low carbon content reduces carbide precipitation. Reduced carbon precipitation during welding helps to keep Hastelloy C276's hardenability in as-welded structures.
Hastelloy C-276 is one of the most often used nickel alloys, given that there are other nickel alloy versions on the market. In the harshest settings and under the most extreme temperature conditions, Hastelloy C276 bolts are commonly implemented. The composition of the substance also includes cobalt, tungsten, iron, silicon, manganese, carbon, and vanadium. This combination gives the C276 Hastelloy Bolts excellent resistance to pitting and crevice corrosion.
Table of Content
The Alloy C276 is the most versatile material mainly found in a wide variety of severe atmospheric conditions. This alloy is very different in its properties. It has excellent corrosion-resistant properties to chloride-containing media, reducing acid, sulfuric flue gases, and oxidizing media.
Composition Of Hastelloy C276
This Hastelloy C276 bolt is the composition of nickel, molybdenum, and tungsten alloy in it. And all these elements are the most popular. Hastelloy C276 Bolts also contains a combination of nickel, chromium, and molybdenum alloy, which is considered the most versatile corrosion-resistant alloy. The high amount of nickel and molybdenum alloy makes the nickel steel alloy more resistant to pitting and crevice. The Chromium alloy exhibits oxidation resistance. These high-graded Hastelloy C276 Bolts are used in many industrial sectors such as petrochemical, waste processing, marine and pharmaceutical, and many more applications. Hastelloy is a superalloy based on nickel that contains only about 50% nickel plus large amounts of molybdenum and chromium.
Hastelloy C276 composition also contains trace amounts of manganese, tungsten, and cobalt. Hastelloy C-276 is defined in weight percent (wt%) and has a minimum and maximum alloying tolerance, like the number of industrial alloys. It is one of the best corrosion-resistant equivalent materials for process industries now on the market. Excellent corrosion resistance for Hastelloy C276 exists in both oxidizing and reducing conditions. We, Dalloyed Works, always use superior quality raw materials, making the best Hastelloy Alloy C276 Bolts. We fabricate these bolts and make them available these bolts at the best affordable price.
UNS N10276 is a nickel-molybdenum-chromium alloy known as Hastelloy C-276. It is highly corrosion-resistant and often used in aggressive chemical environments and high-temperature applications.
What is Hastelloy C276 bolts used for?
UNS N10276 Threaded Bolt are commonly used in various industries for their exceptional corrosion resistance, making them suitable for applications involving strong acids, harsh chemicals, and corrosive environments. They provide high strength and reliability in critical areas where corrosion resistance is paramount, such as chemical processing equipment, petrochemical plants, and offshore drilling platforms.
