B2 Hastelloy® Alloy Plate | Unmatched Resistance to Reducing Environments
✓ HCl Supremacy: Resists 20% boiling hydrochloric acid with <0.05mm/year corrosion rate – 8x lifespan vs. 316L.
✓ Reducing Media Mastery: Immune to corrosion in non-oxidizing sulfuric acid (up to 70%) and phosphoric acid.
✓ Thermal Stability: Maintains integrity from -50°C to 400°C (-58°F to 752°F) under cyclic thermal stress.
✓ Fabrication-Friendly: Ultra-low carbon (0.02% max) minimizes carbide precipitation during welding (ERNiMo-7 filler recommended).
B2 Hastelloy® Alloy Plate (UNS N10665)
Engineered to dominate harsh reducing environments, B2 Hastelloy® alloy plate delivers exceptional resistance to hydrochloric acid, sulfuric acid, and other aggressive reducing media. With a nickel-molybdenum matrix (Ni-65%, Mo-28%, Fe-2% max), this alloy outperforms conventional stainless steels and even 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 oxidizing agents are absent.

FAQ
Q1: How does B2 differ from B3 Hastelloy?
A: B2 excels in pure reducing environments (e.g., HCl without oxidizers), while B3 adds tungsten for improved oxidizing acid resistance at higher cost.
Q2: What welding techniques prevent intergranular corrosion?
A: Use ERNiMo-7 filler with TIG welding, limit heat input to ≤0.8 kJ/mm, and maintain interpass T ≤100°C (per ASME Section IX).
