Thermal Stability

HASTELLOY B3 has significantly improved thermal stability compared to other B-type alloys like B-2. It is less susceptible to the formation of deleterious phases such as Ni4Mo, which can affect ductility and stress corrosion cracking resistance. The time-temperature-transformation (TTT) diagram shows that B3 can withstand higher temperatures for longer periods without forming harmful secondary phases.

Corrosion Resistance

HASTELLOY B3 is highly resistant to:

Hydrochloric Acid

: Exceptional resistance to concentrated hydrochloric acid.

Sulfuric Acid

: High resistance to sulfuric acid, even at elevated temperatures.

Hydrobromic Acid

: Excellent resistance to hydrobromic acid.

Stress Corrosion Cracking (SCC)

: Improved resistance to SCC in chloride-bearing solutions compared to other B-type alloys.

Welding and Fabrication

Weldability

: HASTELLOY B3 is suitable for various welding processes, including Gas Metal Arc (GMA/MIG), Gas Tungsten Arc (GTA/TIG), and Shielded Metal Arc (SMA/Stick) welding.

Heat Treatment

: Solution annealing is recommended to optimize corrosion resistance and ductility. The typical annealing temperature is 1066°C (1950°F), followed by water quenching or rapid air cooling for thin structures.

Formability

: The alloy can be hot forged, hot rolled, hot extruded, and cold formed. However, it requires careful control of strain rates and temperatures due to its sensitivity to strain.

Applications

HASTELLOY B3 wire rod is used in various demanding applications, including:

Chemical Processing

: For components exposed to highly corrosive environments, such as acid handling equipment.

Petrochemical Industry

: For parts that require resistance to both corrosion and high temperatures.

Heat Exchangers

: Due to its thermal stability and corrosion resistance.

Valves and Pumps

: For components that need to withstand aggressive chemical media.

Standards and Specifications

HASTELLOY B3 is available in various forms and is covered by several standards, including:

ASTM B335

: For billet, rod, and bar.

ASTM B333

: For sheet, plate, and strip.

ASTM B622

: For seamless pipe and tube.

ASTM B619

: For welded pipe and tube.

DIN 17744

: For certain applications in the European market.

Packaging and Handling

Wire rods of HASTELLOY B3 are typically packaged to prevent damage and corrosion during transportation. They may be wrapped in oil-coated paper or plastic bags and secured on pallets or in wooden cases to ensure safe handling.

HASTELLOY B3 nickel alloy high-temperature wire rod is a versatile and high-performance material, making it an ideal choice for applications where both corrosion resistance and thermal stability are critical.
