ASTM B564 Hastelloy X Flanges
Amardeep Steel Centre LLP proudly offers a comprehensive range of high-quality ASTM B564 Hastelloy X Flanges tailored to meet the rigorous demands of various industrial applications. Known for their exceptional performance in extreme environments, these flanges are made from Hastelloy X, a nickel-based superalloy that exhibits outstanding resistance to oxidation, corrosion, and high temperatures. This makes them ideal for use in chemical processing, aerospace, and other high-stress applications.
What is ASTM B564 X Hastelloy Flanges?
ASTM B564 X Hastelloy Flanges are specialized components manufactured from Hastelloy X, a nickel-chromium-molybdenum alloy known for its unique combination of oxidation resistance, high-temperature strength, and fabricability. The ASTM B564 specification standardizes the requirements for Hastelloy flanges, ensuring they possess the necessary mechanical properties, chemical composition, and dimensions for industrial use.
X Hastelloy Flanges are designed to connect pipes, valves, pumps, and other equipment within a piping system, providing a secure seal that prevents leaks and withstands high pressures and temperatures. These flanges are essential in industries where harsh conditions are common, such as chemical processing, power generation, and petrochemical refining.

Properties of ASTM B564 X Hastelloy Flanges
Understanding the properties of ASTM B564 X Hastelloy Flanges is essential for selecting the right material for your application. Here’s a closer look at the specific properties that make these flanges stand out:
- Thermal Stability: Hastelloy X maintains its mechanical properties over a wide temperature range, typically from -196°C to 1200°C. This makes it suitable for cryogenic as well as high-temperature applications.
- Oxidation Resistance: The alloy’s composition, which includes chromium, molybdenum, and iron, provides exceptional resistance to oxidation. This is crucial for components exposed to air at high temperatures, such as in industrial furnaces and heat exchangers.
- Creep Resistance: Creep resistance is the ability of a material to resist deformation under mechanical stress over time. X Hastelloy Flanges exhibit excellent creep resistance, making them ideal for long-term use in high-stress environments.
- Weldability: Hastelloy X can be welded using common techniques, including gas tungsten arc welding (GTAW) and gas metal arc welding (GMAW). This property enhances the versatility of the material in manufacturing and assembly processes.
- Corrosion Resistance: The flanges offer excellent resistance to a wide range of corrosive media, including oxidizing and reducing environments. This makes them suitable for use in chemical processing plants, where exposure to harsh chemicals is common.
Advantages of ASTM B564 X Hastelloy Flanges
When it comes to selecting flanges for your industrial needs, the advantages of ASTM B564 X Hastelloy Flanges are undeniable:
- Superior Performance in Extreme Conditions: X Hastelloy Flanges are designed to perform in the harshest environments, including high-temperature and corrosive atmospheres. This reliability ensures safety and efficiency in critical operations.
- Longevity and Durability: The combination of thermal stability, oxidation resistance, and corrosion resistance ensures that these flanges have a long service life. This reduces the need for frequent replacements, leading to cost savings in the long run.
- Versatility: Whether you need flanges for high-temperature furnaces, chemical reactors, or gas turbines, ASTM B564 X Hastelloy Flanges can be tailored to meet your specific requirements. Their ability to be fabricated into various shapes and sizes adds to their versatility.
- Compliance with Industry Standards: ASTM B564 is a widely recognized standard, ensuring that the flanges meet stringent quality and performance criteria. This compliance provides peace of mind, knowing that you are using a product that adheres to global industry standards.
- Cost-Effective: While the initial investment in X Hastelloy Flanges may be higher than other materials, their durability and low maintenance requirements result in significant cost savings over time.
