HB3 Hastelloy® Alloy Coil (UNS N10675)
Engineered to dominate harsh reducing environments, HB3 Hastelloy® alloy coil delivers exceptional resistance to hydrochloric acid (HCl), sulfuric acid (H₂SO₄), and other aggressive reducing media. With a nickel-molybdenum matrix (Ni-65%, Mo-28.5%, Fe-2% max), this alloy outperforms conventional stainless steels and other Hastelloy grades in non-oxidizing conditions. Certified to ASTM B333, ASME SB-333, and NACE MR0175, it is the premier choice for chemical processing, pharmaceutical, and pickling applications where reliability under extreme corrosion is critical.
