Product Specification

High Temperatures alloy ASTM B333 super alloy plate UNS N10665 hastelloy B2 sheet

• Nickel Based corrosion resistance Alloy

Hastelloy B2 exhibits excellent resistance to corrosion due to its specific composition and metallurgical properties. Here are some key reasons why Hastelloy B2 has good resistance to corrosion:

1. Nickel-Molybdenum Alloy: Hastelloy B2 is a nickel-molybdenum alloy with a high nickel content (approximately 65%). Nickel provides excellent corrosion resistance in a wide range of environments, while molybdenum enhances the alloy's resistance to pitting, crevice corrosion, and stress corrosion cracking.

2. Low Carbon Content: Hastelloy B2 has a low carbon content, which reduces the formation of carbide precipitates along grain boundaries. This minimizes the susceptibility to intergranular corrosion, enhancing the overall corrosion resistance of the alloy.

3. Chemical Stability: The specific combination of elements in Hastelloy B2 provides chemical stability in aggressive environments. It is particularly resistant to reducing conditions, making it suitable for applications where corrosion from acids, alkalis, and other chemicals is a concern.

4. Uniform Corrosion Resistance: Hastelloy B2 offers uniform corrosion resistance, meaning it corrodes evenly across its surface when exposed to corrosive substances. This property helps maintain the structural integrity of components made from this alloy.

5. Resistance to Specific Corrosive Agents: Hastelloy B2 is specifically designed to resist corrosion from a wide range of corrosive agents, including sulfuric acid, hydrochloric acid, acetic acid, phosphoric acid, and other aggressive chemicals commonly found in industrial applications.

6. High Temperature Stability: Hastelloy B2 retains its corrosion resistance properties even at elevated temperatures, making it suitable for high-temperature applications where other materials might degrade due to corrosion.

The unique combination of nickel, molybdenum, low carbon content, and other alloying elements in Hastelloy B2 results in its exceptional resistance to corrosion in various challenging environments, making it a preferred choice for applications where corrosion resistance is critical.
