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.
You’ll find these forgings widely utilized in chemical process equipment, pollution control systems, marine hardware, heat exchangers, reactors, and scrubbers, where they provide dependable resistance to aggressive chemicals and high temperatures. Their unique blend of strength, corrosion resistance, and durability makes Hastelloy C22 forgings the go-to choice for critical industrial applications.
