Hastelloy C276 Flanges
Hastelloy is a corrosion-resistant alloy that contains elements like nickel, chromium, and molybdenum. This grade is enriched with high corrosion and temperature resistance. This grade exhibits high strength and ductility, so it is highly used in gas and oil industries. Flanges made of Hastelloy C276 are utilised in machinery and vessels that handle corrosive chemicals and acids. Chemical reactors, distillation columns, and storage tanks all use them.
Hastelloy C276 is highly corrosion-resistant, making it ideal for use in settings where corrosion is risky. It can survive corrosive media such as sulfuric acid, hydrochloric acid, acetic acid, and seawater.
The alloy retains its mechanical strength and corrosion resistance at high temperatures, making it excellent for heat and thermal cycle applications. Hastelloy C276 has excellent weldability and can be welded using various processes, enabling the construction of complicated components.
Hastelloy C276 is a good material for handling harsh chemicals, acids, saltwater, and chlorides because of its exceptional resistance to oxidizing and reducing conditions.
Hastelloy C276 is suitable for high-temperature applications because it retains its mechanical qualities and resistance to corrosion at high temperatures. Because of their adaptable corrosion resistance, these flanges can be used in a variety of industries, such as pulp and paper, waste treatment, petrochemical, chemical processing, and more.
Good mechanical qualities, such as high strength, toughness, and fabricability, enable Hastelloy C276 flanges to endure high-stress situations.
Their broad range of material compatibility allows them to be used in a variety of applications and makes it easier for them to work with other parts of industrial systems.
There are several varieties of Hastelloy C276 flanges, including slip-on, weld neck, blind, socket weld, and threaded flanges, which provide versatility in terms of design and installation techniques.
These flanges all meet industry requirements, including ASTM B564 for forgings, ASTM B462 for welded pipe flanges, and ASTM B574 for forged fittings.
