Located in the heart of Hamilton, New Zealand, Hemi Metals has built a strong reputation for precision and reliability in the specialized field of high-performance alloys. As a trusted manufacturer and supplier, we take great pride in our expertise with Hastelloy C22 forgings. These components are engineered to thrive where others fail, offering our clients across demanding industries a robust solution for their most challenging environments, all supported by our local commitment to exceptional quality and service.
The exceptional resilience of Hastelloy C22 forgings stems from a sophisticated nickel-chromium-molybdenum-tungsten alloy composition. This unique blend grants the material outstanding mechanical strength and toughness, even when exposed to extreme temperatures. It’s this inherent robustness, forged under precise conditions, that allows these components to maintain their structural integrity under immense pressure and stress, making them a fundamentally reliable choice for critical applications.

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.
The primary value of Hastelloy C22 forgings is realized in applications where failure is not an option. You will find these vital components deep within chemical processing plants, managing aggressive acids, and in pollution control scrubbers where they resist corrosive gases. They are equally essential in the demanding environments of oil and gas extraction, pharmaceutical manufacturing, and power generation, serving reliably in everything from reactor vessels to critical pump shafts and valve bodies.
