Starc Metals is a well-respected manufacturer and supplier of Hastelloy C22 Forgings based in Canberra, Australia. We take pride in offering top-notch nickel-chromium-molybdenum-tungsten alloy products that are renowned for their outstanding corrosion resistance and mechanical strength. Our Hastelloy C22 forgings are designed to deliver maximum durability and performance, especially in harsh chemical and marine environments. At Starc Metals, we prioritize high dimensional accuracy, a smooth surface finish, and strict compliance with international standards, ensuring that our precision-forged components are perfect for use in chemical processing, pollution control, and marine engineering sectors.
Typically, Hastelloy C22 Forgings consist of about 56% nickel, 22% chromium, 13% molybdenum, and 3% tungsten, along with trace amounts of iron, cobalt, and vanadium. This carefully balanced composition provides exceptional resistance to both oxidizing and reducing agents, as well as robust protection against pitting, crevice corrosion, and stress corrosion cracking. With a tensile strength ranging from approximately 690 to 785 MPa, Hastelloy C22 maintains its mechanical stability even under high temperatures and corrosive conditions. It also boasts excellent weldability and formability, making it a great choice for intricate forging operations.

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 applications in chemical reactors, heat exchangers, pressure vessels, flue gas scrubbers, and marine hardware that are subjected to highly corrosive environments. They are also essential in pharmaceutical and petrochemical processing equipment, where purity and corrosion resistance are paramount. The alloy’s versatility, combined with its ability to withstand a wide array of harsh chemicals, makes it perfect for demanding industrial applications. With its superior strength, toughness, and corrosion resistance, Hastelloy C22 Forgings from Starc Metals guarantee reliability, longevity, and optimal performance in even the most extreme service conditions.
