ASTM B564 Incoloy 800H Flanges Features

• » Superior Creep Strength: Specifically engineered with a higher carbon content (0.05–0.10%) to provide significantly higher creep and stress-rupture strength at temperatures above 1100°F (593°C).
• » High-Temperature Solution Anneal: Processed at a higher temperature to ensure a larger grain size, which is critical for maintaining structural integrity in extreme heat applications.
• » Oxidation Resistance: Offers excellent resistance to oxidation and scaling under both continuous and cyclic high-temperature conditions.
• » Carburization & Nitriding Defense: Highly effective at preventing carbon and nitrogen absorption, making these flanges suitable for petrochemical and heat-treating atmospheres.
• » Metallurgical Stability: Maintains a stable austenitic structure and remains ductile even after prolonged exposure to the carbide precipitation temperature range.
• » Dual Certification: Often meets the requirements for both Incoloy 800 and 800H, providing versatility for various engineering design specifications.
• » Robust Forging: Manufactured under ASTM B564 standards to ensure uniform grain flow and superior pressure-retaining capabilities in critical piping systems.
• » Precision Sealing: Available in various face types including RTJ and RF to ensure leak-proof performance in high-pressure steam and gas services.
