Mechanical Properties
| Property | Value |
|---|---|
| Tensile Strength | ≥760 MPa |
| Yield Strength (0.2% Offset) | ≥350 MPa |
| Elongation | ≥40% |
| Hardness (Rockwell B) | ≤100 HRBW |
Chemical Properties
Hastelloy B2 Plate demonstrates exceptional resistance to:
- Hydrochloric Acid: Resistant to all concentrations up to boiling point
- Sulfuric Acid: Excellent resistance in moderate concentrations
- Phosphoric Acid: Superior performance in non-oxidizing conditions
- Hydrofluoric Acid: Good resistance in absence of oxidizers
- Organic Acids: Excellent resistance to most organic acids
The alloy B2 material performs exceptionally well in reducing environments but may be susceptible to attack in oxidizing media. The high molybdenum content provides outstanding protection against “knife-line” and “stress” corrosion cracking in chemical processing applications.
Things to Note (Limitations)
While the Hastelloy B2 Plate is a powerhouse, consider these limitations:
- Avoid use in oxidizing environments to prevent rapid corrosion
- Not recommended for temperatures exceeding 1000°F (538°C) for prolonged periods
- Susceptible to embrittlement if not annealed after heavy cold working
Corrosion Data for Hastelloy B2 Material
This hastelloy material offers robust protection:
- Atmospheric Corrosion: Highly resistant in standard conditions
- Mild Chemical Exposure: Excellent performance against organic acids and chloride-induced stress corrosion
- Tested Resistance: Minimal corrosion rate in boiling hydrochloric acid (up to 20%)
Welding and Manufacturing Tips
Welding the Hastelloy B2 Sheet is straightforward with the right approach:
- Recommended Methods: Gas Tungsten Arc (GTAW), Gas Metal Arc (GMAW), or Shielded Metal Arc (SMAW)
- Tips: Use matching B2 filler metals; resists grain boundary carbide precipitation in weld zones
- Forming: Cold forming possible; anneal after >7% deformation to restore properties
Our China factory ensures precision manufacturing for seamless integration into your processes.
What Customers Say About Our Hastelloy Material
Frequently Asked Questions
Q: How does Hastelloy B2 Sheet compare to Hastelloy C276?
A: The Hastelloy B2 Sheet excels in reducing environments, particularly against hydrochloric and sulfuric acids, making it ideal for specific chemical applications. In contrast, Hastelloy C276 is better suited for oxidizing conditions, offering broader resistance to mixed corrosive agents.
Â
Q: Does the Bright Finish serve a functional purpose?
A: Yes, beyond enhancing its visual appeal, the Bright Finish improves corrosion resistance by reducing surface imperfections and makes cleaning easier, which is a practical benefit in demanding environments.
Â
Q: Can this hastelloy plate withstand high temperatures?
A: It performs well up to 1000°F (538°C) for short periods, but prolonged exposure at extreme heat may reduce its effectiveness. For high-temperature applications, alloys like Hastelloy X are more suitable.
Â
Q: What industries benefit most from Hastelloy B2 Sheet?
A: Industries like chemical processing, pharmaceuticals, and oil and gas rely on this b2 material for its superior resistance to reducing acids and durability in aggressive settings.
Â
Q: How can I request a quote from your company?
A: Contact our with your specifications, such as thickness and quantity, and we’ll provide a tailored Hastelloy B2 Sheet price within 24 hours.
Â
Q: Is welding the Hastelloy B2 Sheet difficult?
A: No, it’s quite manageable with methods like GTAW or GMAW using B2 filler metals. Its resistance to weld-zone corrosion simplifies the process, though annealing may be needed after extensive cold forming.
