Chemical Properties
The Hastelloy B2 Bar exhibits distinct chemical properties that make it a standout choice for specific corrosive environments:
- Acids: The Hastelloy B2 Bar offers exceptional resistance to reducing acids, such as hydrochloric acid (HCl), across all concentrations and temperatures up to boiling. It also performs admirably against sulfuric acid (H₂SO₄) and phosphoric acid (H₃PO₄) in reducing conditions, making it ideal for Hastelloy B2 Round Bar applications in acid-heavy industries. However, its resistance weakens in oxidizing acids like nitric acid (HNO₃).
- Alkalis: It provides moderate resistance to alkaline solutions, such as sodium hydroxide (NaOH), particularly in mild conditions. While not its strongest suit, the B2 Round Bar can still function effectively in less aggressive alkaline environments.
- Limitations: The Hastelloy B2 Bar is less effective in oxidizing media or environments with ferric or cupric salts, where pitting or accelerated corrosion may occur. To maintain its integrity, avoid using it in settings with strong oxidizers or chlorine-rich conditions.
Things to Note (Limitations)
The Hastelloy B2 Bar has constraints:
- Oxidizing Media: Susceptible to corrosion in oxidizing acids or chlorine-rich settings.
- High Temperatures: Strength may drop above 800°C.
- Cost: Higher than stainless steel due to alloy content.
Our China distributor can suggest alternatives if needed.
Corrosion Data
- Atmospheric: Good resistance in dry or mild conditions.
- Reducing Acids: Excellent against hydrochloric and sulfuric acids.
- Oxidizing Environments: Fair; avoid prolonged exposure to oxidizers.
This suits Hastelloy B2 Round Bar for reducing chemical applications.
Welding and Manufacturing Tips
Welding Hastelloy B2 Bar is efficient:
- TIG Welding: Preferred for precision on B2 Round Bar.
- MIG Welding: Suitable for thicker Hastelloy B2 Round Bar sections.
Tips:
- Use B2 or nickel-based filler metals to maintain corrosion resistance.
- Minimize heat input to avoid sensitization.
- Machining requires sharp tools and coolant for Hastelloy B2 Bar.
