Aung Metals, a prominent manufacturer and supplier located in Naypyidaw, Myanmar, focuses on crafting top-notch Hastelloy C22 Forgings that are built to resist corrosion and perform well under high temperatures. These forgings are specifically designed to handle tough chemical environments, including both oxidizing and reducing agents, making them perfect for industries like chemical processing, marine, and petrochemicals. Aung Metals prides itself on precision manufacturing, ensuring dimensional accuracy and strict compliance with international standards, resulting in Hastelloy C22 Forgings that offer remarkable strength, durability, and reliability for critical industrial and engineering tasks.
Hastelloy C22 Forgings are mainly made up of nickel, chromium, and molybdenum, with small amounts of tungsten, iron, and cobalt added in. This unique alloy mix gives them exceptional resistance to pitting, crevice corrosion, and stress-corrosion cracking, even in highly corrosive settings. On the mechanical side, these forgings boast a tensile strength of about 690 MPa and a yield strength of around 275 MPa, along with impressive ductility, toughness, and thermal stability. Their well-balanced alloy chemistry guarantees consistent performance, even when faced with extreme chemical and thermal challenges.

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.
These Hastelloy C22 Forgings find their place in industries that require outstanding corrosion resistance and strength. They are perfect for making heat exchangers, reactors, piping systems, valves, pumps, and equipment for chemical processing. Additionally, they are utilized in marine and offshore components, pollution control systems, and pharmaceutical machinery, thanks to their ability to withstand strong oxidizing and reducing acids. With excellent machinability, weldability, and long-lasting durability, Hastelloy C22 Forgings deliver reliable performance in some of the toughest industrial environments.
