All these elements together make it extremely versatile for applications involving exposure to both oxidation and reduction conditions across a wide range of temperatures and concentrations.

The processing is also key to achieving the right properties. ASTM B575 Hastelloy C22 2B Finish go through careful heat treatment and annealing, which gives this alloy improved ductility and forgeability while maintaining high strength. The plates can be shaped or forged into different forms for use in various applications and industries without losing corrosion resistance. Proper work hardening preserves strength, while careful annealing prevents cracking under stress and maintains the versatility of use.

With its combination of corrosion resistance, heat resistance and mechanical strength, Hastelloy C22 finds many critical uses across chemical processing, petrochemical, oil & gas, pollution control and other high-tech industries. It is uniquely suited for making process equipment and structures that need to withstand very corrosive hot acids like sulfuric, hydrochloric and phosphoric acids. The material retains adequate impact and ductility strength even in subzero environments of up to 150 degrees F, which allows its use in applications with extreme temperature fluctuations.

Wet chlorine environments rapidly damage many metals through stress corrosion cracking, but Hastelloy C22 can withstand chloride pitting and subsequent cracking failure modes. This makes it invaluable for use in marine applications as well as processes involving chlorine gas, liquids or solutions.
