To determine if Hastelloy B2 forgings meet your needs, evaluate their resistance to corrosion in aggressive chemical environments and their mechanical properties at the operating temperature. Perform tests such as tensile, impact, and corrosion resistance tests for assurance.
The forging process for Hastelloy B2 typically takes several hours, depending on the complexity of the part and the size of the material. It includes heating, shaping, cooling, and any necessary post-forging treatments.
The ideal temperature range for forging Hastelloy B2 is between 2,100°F and 2,300°F (1,149°C to 1,260°C). This range ensures optimal material flow and avoids excessive grain growth.
Hastelloy B2 Forgings find extensive use in industries that demand reliable materials for highly corrosive conditions. They are commonly utilized in chemical processing plants for components like reactors, heat exchangers, evaporators, and distillation equipment that come into contact with hydrochloric acid and reducing chemicals. In the pharmaceutical and food processing sectors, they are used for equipment that needs to endure harsh cleaning agents. The petrochemical industry relies on Hastelloy B2 for pumps, valves, and piping systems that handle strong acids.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
