ASTM B366 WPHC276 / UNS N10276 Nickel Alloy Eccentric Reducer Hastelloy Pipe Fittings
ASTM B366 WPHC276 (UNS N10276) Nickel Alloy Eccentric Reducer is a factory-made, wrought pipe fitting manufactured to ASTM B366 specifications. It is produced from a nickel-chromium-molybdenum-tungsten alloy (commonly known as Hastelloy C276). The advantages-- 1. Excellent corrosion resistance in harsh environments (e.g., sulfuric acid, hydrochloric acid, chlorine). 2. Resists pitting, crevice corrosion, and stress-corrosion cracking. 3. Performs well in high-temperature and high-pressure conditions.
The fitting features an eccentric (offset) conical design, which reduces the pipe bore from a larger diameter to a smaller diameter while maintaining a continuous flat top or bottom alignment. It is delivered in the solution-annealed and rapidly quenched condition to retain maximum ductility and corrosion resistance, free from harmful intermetallic precipitates.

The "3 Red Flags" that force you to pick Hastelloy C276:
| Red Flag | Specific Conditions | Why 316L/Others Die |
|---|---|---|
| 1. Wet Hydrochloric Acid (HCl) or Wet Chlorine | Any temperature above ambient, or any concentration > 5%. | 316L's molybdenum is chemically ripped out. The pipe dissolves like sugar in water. C-276 is the standard go-to. |
| 2. Hot, Concentrated Sulfuric / Mixed Acids | Temperatures > 150°F (65°C) with strong oxidizers or reducers. | 316L forms a weak passive film here. C-276 survives due to its massive Mo+W content. |
| 3. High Chlorides + Low pH + High Heat (> 180°F) | Found in Flue Gas Desulfurization (FGD) scrubbers or geothermal brines. | 316L gets pinhole pitting and Stress Corrosion Cracking (SCC) in weeks. C-276 resists both due to its Ni-Cr-Mo matrix. |
Application
1. Chemical Processing (The "Acid Factory")
2. Flue Gas Desulfurization (FGD) – Power Plants & Waste-to-Energy
3. Offshore Oil, Gas, and Geothermal (Sour Service)
4. Pulp & Paper (Bleaching Plants)
5. Nuclear Waste Treatment & Reprocessing
