Product Description
Hastelloy C276 (UNS N10276) Large Diameter Flanges
ASTM B564 Forged Corrosion-Resistant Flanges for Industrial Applications
Hastelloy C276 (UNS N10276) large diameter flanges are manufactured in strict accordance with ASTM B564, delivering exceptional resistance to corrosion, pitting, crevice attack, and stress corrosion cracking in highly aggressive environments. Designed for demanding industrial applications, these forged flanges provide superior mechanical strength, structural integrity, and long-term reliability under extreme chemical, thermal, and pressure conditions.
Material Overview - Hastelloy C276 (UNS N10276)
Hastelloy C276 is a nickel-chromium-molybdenum alloy with excellent resistance to:
- Chloride-induced pitting and crevice corrosion
- Stress corrosion cracking
- Oxidizing and reducing acids
- Wet chlorine gas and hypochlorite environments
- Sulfuric, hydrochloric, and phosphoric acids
Its low carbon content minimizes carbide precipitation during welding, ensuring outstanding corrosion resistance in welded structures.
Manufacturing Standard
- ASTM B564 - Forged Nickel Alloy Flanges
- Available per ASME B16.5 / ASME B16.47
- Custom dimensions supported for large-diameter applications
All flanges are forged from high-quality billet or ring forgings, followed by precision machining and strict quality inspection.
Product Features
- Large diameter capability (custom sizes available)
- Excellent high-temperature strength
- Outstanding resistance to localized corrosion
- Superior weldability and fabrication performance
- Tight dimensional tolerances
- 100% material traceability
Available Types
- Weld Neck Flanges
