Yes, Hastelloy C22 can be forged into custom shapes, as it has good formability and strength at elevated temperatures. However, it requires precise control during the forging process to maintain its properties.
The ideal temperature range for forging Hastelloy C22 is between 2,100°F (1,150°C) and 2,300°F (1,260°C). This ensures optimal formability and minimizes the risk of damaging the material's properties.
The forging process for Hastelloy C22 typically takes several minutes to hours, depending on the complexity and size of the part. The heating and cooling cycles also influence the total time required for forging.
Hastelloy C22 Forgings find extensive use in chemical processing applications, such as reactors, heat exchangers, piping, and pressure vessels that come into contact with highly corrosive substances. The alloy’s adaptability makes it ideal for pollution control equipment, flue gas scrubbers, and pharmaceutical manufacturing. Additionally, it plays a crucial role in the aerospace and power generation sectors for components that face oxidative and reductive stress. In marine settings, Hastelloy C22 is utilized in seawater handling systems and offshore equipment. Its outstanding corrosion resistance and durability make it a preferred choice in these demanding applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
