Known for its exceptional corrosion resistance, it is often used in piping systems handling acidic, chloride-rich, and high-temperature fluids.
Standard: ASTM B564 / ASME B16.5 / MSS SP-44
Material: Nickel-Molybdenum-Chromium Alloy (Hastelloy C276, UNS N10276)
Size Range: DN15 – DN600 (½" – 24")
Pressure Rating: Class 150 – Class 2500
Facing Type: RF / FF / RTJ
Type: Slip-On (SORF) Flange
2. Chemical Composition (C276)
| Element | Content (%) |
|---|---|
| Nickel (Ni) | Balance |
| Molybdenum (Mo) | 15.0 – 17.0 |
| Chromium (Cr) | 14.5 – 16.5 |
| Iron (Fe) | 4.0 – 7.0 |
| Tungsten (W) | 3.0 – 4.5 |
| Cobalt (Co) | ≤ 2.5 |
| Manganese (Mn) | ≤ 1.0 |
| Carbon (C) | ≤ 0.01 |
| Silicon (Si) | ≤ 0.08 |
| Vanadium (V) | ≤ 0.35 |
The high nickel and molybdenum content provides excellent resistance to pitting, crevice corrosion, and oxidizing or reducing media, while chromium enhances resistance to oxidation.
