B2 Hastelloy® Alloy Coil (UNS N10665)
Engineered to dominate harsh reducing environments, B2 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%, 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 go-to material for chemical processing, pharmaceutical, and pickling applications where reliability under extreme corrosion is non-negotiable.

FAQ
Q1: How does B2 compare to B3 Hastelloy?
A: B2 excels in pure reducing environments (e.g., HCl without oxidizers) with lower cost, while B3 adds tungsten for improved oxidizing acid resistance.
Q2: What welding filler metals are recommended?
A: Use ERNiMo-7 (TIG) with 0.5–1.0 kJ/mm heat input and maintain interpass T ≤100°C (per ASME Section IX). Post-weld heat treatment is not required.
