HB3 Hastelloy® Alloy Plate | Superior High-Temperature & Corrosion Resistance
✓ HCl Supremacy: Resists 20% boiling hydrochloric acid with <0.01mm/year corrosion rate – 10x lifespan vs. B2 alloy.
✓ Thermal Stability: Maintains strength from **-50°C to 400°C (-58°F to 752°F)** under cyclic thermal stress.
✓ Reducing Media Mastery: Immune to hydrogen embrittlement in H₂S-saturated environments (NACE TM0177 compliant).
✓ Fabrication-Ready: Ultra-low carbon (0.01% max) prevents carbide precipitation during welding (ERNiMo-10 filler recommended).
HB3 Hastelloy® Alloy Plate (UNS N10675)
Engineered to dominate extreme environments combining high temperatures and aggressive chemical exposure, HB3 Hastelloy® alloy plate excels in hydrochloric acid, sulfuric acid, and reducing media. With a nickel-molybdenum-chromium matrix (Ni-65%, Mo-28.5%, Cr-1.5%), this specialized alloy delivers unmatched resistance to hydrochloric acid even at elevated temperatures, outperforming conventional Hastelloy grades like B2 and B3. Certified to ASTM B333, ASME SB-333, and NACE MR0175, it is the ultimate solution for chemical reactors, pickling systems, and hydrochloric acid recovery units.
