Excellent resistance to Sulfuric acid UNS N10665 hastelloy B2 alloy tube with ASTM B622 standard

• Nickel Based corrosion resistance Alloy

Hastelloy B2 is a nickel-molybdenum alloy known for its excellent resistance to reducing environments such as sulfuric acid. It offers superior corrosion resistance in a wide range of aggressive chemicals. The chemical composition of Hastelloy B2 typically includes nickel, molybdenum, iron, chromium, and other elements to enhance its properties.

Hastelloy B2 is typically used in conditions where it is exposed to aggressive chemical environments, especially reducing conditions. Some common conditions where Hastelloy B2 is used include:

1. Sulfuric acid environments: Hastelloy B2 is highly resistant to sulfuric acid solutions, including those containing concentrations of up to 70%. It is often used in industries where sulfuric acid is a primary chemical used in processing.

2. Acetic acid environments: Hastelloy B2 is also resistant to acetic acid and acetic anhydride, making it suitable for applications in industries where these chemicals are present, such as in the production of chemicals, plastics, and pharmaceuticals.

3. Phosphoric acid environments: Hastelloy B2 offers good resistance to phosphoric acid, which is commonly used in the fertilizer industry and other chemical processes.

4. Hydrochloric acid environments: While not as resistant to hydrochloric acid as some other Hastelloy alloys, Hastelloy B2 can still be used in environments where hydrochloric acid is present at moderate concentrations.

5. Chloride-containing environments: Hastelloy B2 provides good resistance to chloride-induced stress corrosion cracking, making it suitable for applications where exposure to chloride ions is a concern.

Overall, Hastelloy B2 is chosen for its excellent corrosion resistance in reducing chemical environments, making it ideal for applications where other materials may fail due to corrosion.
