800H Special Material Flanges in Various Industries with Material for Secure Connections
Crafted from Incoloy 800H (UNS N08810), these advanced flanges are engineered to thrive in extreme high-temperature, corrosive, and oxidizing environments, making them indispensable for petrochemical refineries, power generation, heat treatment furnaces, and nuclear reactors. With a unique nickel-iron-chromium alloy composition (Ni 30-35%, Cr 19-23%), they deliver exceptional resistance to oxidation, carburization, and sulfidation at temperatures up to 1150°C (2102°F), ensuring leak-proof reliability in critical systems exposed to steam, hydrocarbon gases, and molten salts.
Key Benefits
✅ Superior High-Temperature Performance:
Outstanding Creep Resistance: Maintains structural integrity under prolonged stress at elevated temperatures, ideal for ethylene cracking furnaces, reformers, and radiant tubes.
Oxidation & Carburization Defense: Chromium content forms a protective oxide layer, resisting scaling and degradation in CO-rich or sulfur-containing atmospheres.
✅ Robust Mechanical Durability:
High Tensile Strength (≥450 MPa) and thermal fatigue resistance ensure reliability in cyclic heating/cooling applications and high-pressure systems (Class 150 to 2500).
Excellent resistance to chloride-induced stress corrosion cracking (SCC) in marine and chemical environments.
✅ Cost-Efficient Longevity:
Slashes downtime and replacement costs with a lifespan 3-5x longer than standard 304H/310S steels in coking, pyrolysis, and hydrogen production units.
Operates reliably from -200°C to 1150°C (-328°F to 2102°F), suitable for cryogenic LNG systems to high-heat industrial furnaces.
✅ Global Compliance & Traceability:
Manufactured to ASTM B407, ASME SB-407, EN 1092-1, and PED 2014/68/EU standards, with full material traceability (MTC 3.1) and ISO 9001/API Q1 certifications.
Compliant with NACE MR0175 for sour service (H₂S environments) and ASME III for nuclear applications.
✅ Customizable Solutions:
Types: Weld neck, slip-on, blind, lap joint, and threaded designs.
Sizes: DN15 to DN2000, with tailored pressure ratings (PN10 to PN400), face finishes (RF/RTJ/FF), and bore alignments.
Post-Treatment: Solution annealing, shot blasting, or pickling for enhanced surface stability.
