Exceptional Corrosion Resistance: Withstands highly aggressive chemicals, including hydrochloric, sulfuric, and phosphoric acids.
Superior Thermal Stability: Maintains strength and corrosion resistance even at high temperatures.
High Mechanical Strength: Ensures durability in harsh environments and prevents stress corrosion cracking.
Excellent Fabricability: Easily machined, welded, and processed without significant carbide precipitation.
Hastelloy B-3 (UNS N10675 / DIN 2.4600) is an advanced nickel-molybdenum alloy optimized for superior thermal stability and resistance to non-oxidizing acids. Compared to predecessors like Hastelloy B-2, it offers improved resistance to pitting, stress corrosion cracking (SCC), and knife-line attack while maintaining excellent fabricability and weldability in the heat-affected zone.
Our factory-produced Hastelloy B-3 round bars provide outstanding performance across all concentrations and temperatures of hydrochloric acid, sulfuric acid, acetic acid, formic acid, phosphoric acid, and other reducing media. Ideal for chemical processing equipment, these bars combine high strength, ductility, and long-term corrosion resistance, making them the preferred choice for harsh industrial applications worldwide.

FAQs:
What makes Hastelloy B-3 superior for corrosion resistance?
Hastelloy B-3 offers exceptional resistance to hydrochloric acid at all concentrations and temperatures, plus strong performance against other non-oxidizing acids, with better thermal stability than B-2.
What are the typical dimensions and specifications available?
We supply round bars in a wide range of diameters per ASTM B335 / UNS N10675. Custom sizes and finishes (e.g., bright, black, or machined) are available upon request.
Is Hastelloy B-3 suitable for welding?
Yes. Its improved thermal stability provides excellent weldability with minimal risk of sensitization or knife-line corrosion in the heat-affected zone.
What industries benefit most from these bars?
Primarily chemical processing, pharmaceuticals, petrochemicals, and acid production facilities where resistance to reducing acids and pitting is critical.
How does it compare to Hastelloy B-2 or stainless steels?
B-3 provides superior thermal stability, better resistance to SCC and pitting, and improved fabricability while maintaining comparable or better acid corrosion resistance.
