What is ASTM B564 C4 Hastelloy Flanges?
ASTM B564 C4 Hastelloy Flanges are flanges manufactured using Hastelloy C4, a nickel-chromium-molybdenum alloy known for its exceptional resistance to oxidation and corrosion. This specification (ASTM B564) covers nickel alloy flanges, fittings, valves, and other components designed for high-pressure applications. The flanges produced under this specification are suitable for use in various industries, such as chemical processing, petrochemical, oil and gas, pharmaceuticals, and more.
The Hastelloy Flanges ASTM B564 C4 are particularly valued for their resistance to localized corrosion, stress corrosion cracking, and pitting in both reducing and oxidizing environments. These flanges are ideal for applications involving severe chemical conditions, where durability and longevity are crucial.

Properties of ASTM B564 C4 Hastelloy Flanges
- Corrosion Resistance: One of the standout properties of ASTM B564 C4 Hastelloy Flange is their excellent resistance to a wide range of corrosive environments. These flanges offer unparalleled protection against pitting, crevice corrosion, and intergranular corrosion, particularly in high-temperature applications.
- High Temperature Stability: Hastelloy ASTM B564 C4 Flanges retain their mechanical properties even at elevated temperatures. The alloy remains stable and resistant to embrittlement or cracking up to temperatures as high as 1040°C (1904°F).
- Mechanical Strength: The C4 Hastelloy Flanges possess high tensile strength and excellent toughness, making them suitable for high-stress environments. They can withstand significant mechanical loads and pressures, which makes them ideal for critical applications.
- Weldability: The alloy’s composition allows for excellent weldability, making it easier to fabricate ASTM B564 C4 Hastelloy Flanges without compromising their structural integrity or corrosion resistance. This is particularly beneficial in applications where welding is required.
- Resistance to Reducing and Oxidizing Media: The unique chemical composition of Hastelloy Flanges ASTM B564 C4 provides robust resistance to both reducing and oxidizing environments, including those containing chloride, nitric acid, and sulfuric acid. This makes them highly versatile across various industries.
Advantages of ASTM B564 C4 Hastelloy Flanges
- Versatility in Application: Due to their excellent resistance to a variety of harsh environments, ASTM B564 C4 Hastelloy Flange are versatile and can be used in multiple applications, ranging from chemical processing to power generation. Their ability to perform under both reducing and oxidizing conditions makes them a preferred choice across industries.
- Long Service Life: The combination of high corrosion resistance, mechanical strength, and temperature stability ensures that these flanges have a long service life. This longevity reduces the frequency of replacements and maintenance, leading to cost savings over time.
- Cost-Effective: Despite the initial investment, C4 Hastelloy Flanges prove to be cost-effective due to their durability and minimal maintenance requirements. The high performance of these flanges in harsh environments ensures a good return on investment over time.
- Superior Performance in Extreme Conditions: These flanges are designed to perform in extreme conditions, such as high temperatures, high pressure, and corrosive environments. Their ability to withstand such conditions without degradation makes them an ideal choice for critical applications.
- Customizability: At Amardeep Steel Centre LLP, we offer Hastelloy ASTM B564 C4 Flanges in various sizes, dimensions, and specifications to meet your specific requirements. Custom flanges can be manufactured to fit unique or non-standard applications.
