| High Light | Hastelloy C276 large diameter flanges ，ASTM B564 forged nickel alloy flanges ，corrosion-resistant industrial flanges with warranty | ||
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.
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.
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.
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
Weld Neck Flanges
Slip-On Flanges
Blind Flanges
Custom Forged Ring Flanges
Pressure ratings and dimensions can be manufactured according to project requirements.
Our ASTM B564 Hastelloy C276 flanges are widely used in:
Chemical processing plants
Oil & gas offshore platforms
Flue gas desulfurization (FGD) systems
Waste treatment facilities
Petrochemical reactors and piping systems
Marine engineering equipment
Each flange undergoes:
Chemical composition verification
Mechanical property testing
Ultrasonic inspection (UT)
Dimensional inspection
Surface quality examination
Mill test certificates (MTC) are provided upon request.
