B3 Hastelloy® Alloy Coil | Advanced Corrosion Resistance for Mixed Reducing-Oxidizing Environments

✓ HCl + Oxidizer Dominance: Resists 20% boiling HCl with 500 ppm FeCl₃ at <0.015mm/year corrosion rate – 3x durability vs. B2.

✓ Thermal Stability: Maintains integrity from -50°C to 400°C (-58°F to 752°F) under cyclic thermal stress.

✓ Tungsten-Enhanced Toughness: 1.5% W minimizes pitting in chloride-rich media (PREN ≥65).

✓ Precision Cold Rolling: Tight tolerance ±0.02mm thickness** for seamless fabrication into tanks, heat exchangers, and piping.

B3 Hastelloy® Alloy Coil (UNS N10675)

Engineered to excel in aggressive environments combining reducing and oxidizing conditions, B3 Hastelloy® alloy coil leverages a nickel-molybdenum-tungsten matrix (Ni-65%, Mo-28.5%, W-1.5%) to deliver unrivaled resistance to hydrochloric acid (HCl), sulfuric acid (H₂SO₄), and trace oxidizers. Certified to ASTM B333, ASME SB-333, and NACE MR0175, this alloy outperforms B2 and other Hastelloy grades in mixed-acid media, offering 2x the lifespan of B2 in environments contaminated with chlorides or oxidizing ions like Fe³⁺/Cu²⁺. Ideal for chemical reactors, pickling systems, and sour gas applications.
