ASTM B366 C276 LWNRF Flange
ASTM B366 C276 flanges refer to a specific type of flange that is made from the alloy Hastelloy C-276, as per the specifications outlined by the American Society for Testing and Materials (ASTM). Hastelloy C-276 is a nickel-chromium-molybdenum alloy known for its exceptional corrosion resistance in a wide range of environments, including high-temperature and high-corrosion conditions.
Hastelloy C-276 offers outstanding resistance to a variety of corrosive media, including acids, alkalis, and chloride ions. This makes it suitable for use in industries where aggressive chemicals or environmental conditions are present, such as chemical processing, petrochemicals, and marine applications.
Due to its comprehensive resistance properties, C-276 flanges can be used in a wide array of industries and applications where other materials might not be suitable. They are often used in applications involving sulfuric acid, hydrofluoric acid, chlorides, and salt solutions.
Hastelloy C-276 can withstand high temperatures without losing its strength or corrosion resistance, making it an ideal choice for high-temperature applications as well.
These flanges offer good mechanical properties, including high strength at both room and elevated temperatures, making them suitable for applications requiring tight sealing and durability.
ASTM B366 C276 flanges can be fabricated into various configurations and sizes, allowing for flexibility in design and installation. They may come in different forms like weld neck, lap joint, slip-on, etc., depending on the specific application requirements.
The production of these flanges adheres to stringent quality control measures, ensuring consistent material composition, mechanical properties, and surface finish, which are critical for reliable performance in critical applications.
ASTM B366 C276 flanges are specialized components designed for harsh industrial environments where superior corrosion resistance and mechanical integrity are paramount.
