ASTM B564 UNS N10276 / Hastelloy C276 Weld Neck Flange, Raised Face (RF) Class 150/300/600, For Seawater Desalination

Introduction of ASTM B564 UNS N10276 / Hastelloy C276 Weld Neck Flange

Our Hastelloy C276 (UNS N10276) Weld Neck Flanges are manufactured in accordance with ASTM B564 and ASME B16.5/B16.47.

This nickel‑molybdenum‑chromium alloy provides excellent resistance to uniform corrosion, pitting, crevice corrosion, and stress corrosion cracking in extreme environments. Forged, solution annealed, and strictly inspected, our WNRF flanges feature high mechanical strength, good weldability, and long service life.

They are widely used in oil & gas, refinery, petrochemical, chemical processing, desalination, and flue gas desulfurization system. YUHONG can supply full sizes and pressure classes with EN 10204 3.1/3.2, PMI, NDT, and NACE MR0175 certifications available.

II. Chemical Composition (ASTM B564 / UNS N10276)

Element	Content (%)	Function
Nickel (Ni)	Balance (≥50.99)	Base element, provides fundamental corrosion resistance
Molybdenum (Mo)	15.00 – 17.00	Resists reducing media (hydrochloric acid, sulfuric acid); enhances pitting resistance
Chromium (Cr)	14.50 – 16.50	Forms protective oxide film; resists oxidizing media (nitric acid, wet chlorine)
Iron (Fe)	4.00 – 7.00	Provides strength
Tungsten (W)	3.00 – 4.50	Enhances resistance to localized corrosion (pitting/crevice corrosion)
Cobalt (Co)	≤ 2.50	High-temperature stability
Carbon (C)	≤ 0.010	Ultra-low carbon content prevents carbide precipitation during welding, avoiding intergranular corrosion

Key Performance Advantages of ASTM B564 Hastelloy C276 Weld Neck Flange

Corrosion Resistance

- Resists strong acids (HCl, H₂SO₄, H₃PO₄) and chloride-induced pitting, crevice corrosion, and SCC. PREn ~69, far exceeding stainless steel.
- Tungsten (W) addition ensures stability in mixed acid environments.

Thermal Stability

- Service range: -196°C to 1040°C.
- Ultra-low carbon allows welding without post-weld heat treatment (PWHT) and eliminates intergranular corrosion risk.

Mechanical Connection

- Weld Neck (WN): Tapered neck ensures smooth stress transition and high fatigue resistance—ideal for high-pressure, high-temperature, and cyclic conditions.
- Raised Face (RF): Universal sealing compatible with various gaskets (e.g., spiral wound, graphite).
