B3 Hastelloy® Alloy Pipe | Unmatched Performance in Mixed Acid & High-Temperature Environments
✓ Hybrid Acid Resistance: Excels in 20% HCl + 5% HNO₃ at 80°C (176°F) with <0.03mm/year corrosion rate – industry-leading performance in mixed acid environments.
✓ Thermal Stability: Maintains integrity from -50°C to 450°C (-58°F to 842°F) under rapid thermal cycling, eliminating sensitization risks.
✓ Fabrication-Friendly: Ultra-low carbon (0.01% max) and controlled silicon (0.1% max) minimize carbide precipitation during welding.
✓ Precision Engineering: Seamless and welded pipes with ±1% OD/ID tolerance and Ra ≤0.4μm internal finish for high-purity fluid systems.
B3 Hastelloy® Alloy Pipe (UNS N10675)
Engineered to conquer the harshest reducing and mildly oxidizing environments, B3 Hastelloy® alloy pipe combines a nickel-molybdenum-chromium-tungsten matrix (Ni-65%, Mo-28.5%, Cr-1.8%, W-1.5%) to deliver superior resistance to hydrochloric acid (HCl), sulfuric acid (H₂SO₄), and mixed acid-chloride media. Certified to ASTM B622, ASME SB-622, and NACE MR0175, this advanced alloy outperforms traditional B2 Hastelloy in thermal stability and resistance to localized corrosion, offering 2x the lifespan of B2 in cyclic high-temperature HCl and phosphoric acid applications.
