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.
The primary use for Hastelloy B2 forgings is within the chemical processing industry, where they are essential for constructing reactors, valves, pumps, and piping systems that handle aggressive hydrochloric and sulfuric acids. You will also find these robust components in pollution control equipment, pharmaceutical manufacturing, and pickling operations. They are the material of choice for any application where resisting severe corrosion is paramount to safety, efficiency, and the long-term success of your project.
