Hastelloy B-2 N10665/2.4617/ NS3202 Plate/Strip/Bar/Rod/Forging Suitable For Acidic Environments In Heat Recovery Systems
Hastelloy B-2 (UNS N10665 / W.Nr. 2.4617 / NS3202) is a nickel-molybdenum alloy known for its excellent resistance to reducing environments such as hydrochloric, hydrobromic, and sulfuric acids. It has exceptional resistance to pitting, stress corrosion cracking, and knife-line attack, making it ideal for chemical processing industries. Available in plate, strip, bar, rod, and forging forms, Hastelloy B-2 maintains high strength and toughness across a wide temperature range. It is not recommended for oxidizing media but performs exceptionally in controlled environments. The alloy is easily fabricated and welded, though care must be taken during heat treatment. Typical applications include reactors, heat exchangers, and piping in aggressive chemical service.

Key Features:
1. Excellent Corrosion Resistance
Superior resistance to hydrochloric acid (HCl) at all concentrations and temperatures.
Outstanding resistance to sulfuric, acetic, formic, and phosphoric acids.
Effective against wet hydrogen chloride and acidic chloride environments.
2. Resistance to Stress Corrosion Cracking
Low carbon and silicon content helps minimize carbide precipitation during welding, reducing the risk of intergranular corrosion.
Excellent resistance to stress corrosion cracking and pitting corrosion.
3. High Thermal Stability
Maintains strength and corrosion resistance at elevated temperatures up to around 850°C (1560°F).
4. Good Fabricability
Can be hot and cold worked, machined, welded, and forged.
Commonly processed using standard methods, but must avoid excessive cold working to prevent work hardening.
5. Purity and Weld Integrity
Improved metallurgy over earlier Hastelloy grades: cleaner structure, improved thermal stability, and less susceptibility to fabrication-induced problems.
6. Typical Forms
Supplied as plates, strips, bars, rods, and forgings for flexibility across industrial applications.
General Characteristics
Excellent resistance to hydrochloric acid at all concentrations and temperatures.
Resists pitting, stress corrosion cracking, and crevice corrosion.
Not suitable for oxidizing environments (e.g., nitric acid, ferric/ cupric salts).
Applications by Form
Plate & Strip
Used in large-area corrosion-resistant structures:
Reactor vessels and columns in chemical processing
Acid production equipment
Heat exchanger shells
Lining for tanks and containers transporting or storing strong acids
Bar & Rod
Commonly machined into components needing mechanical strength and corrosion resistance:
Pump shafts and impellers
Valve bodies and stems
Fasteners for corrosive service
Support pins and stirrers in acidic environments
Forgings
Ideal for custom-shaped, high-integrity parts:
Flanges, fittings, and pressure vessel parts
Custom components for reactors and acid handling systems
Hammered or pressed parts used in critical applications requiring good metallurgical properties
Industries That Use Hastelloy B-2
Chemical processing
Pharmaceutical manufacturing
Petrochemical plants
Pulp & paper industry (where bleaching uses strong acids)
Waste treatment systems handling strong reducing chemicals
