HC-22 Alloy: High-Strength, Corrosion-Resistant Metal For Demanding Industrial Applications.
The following is a detailed product description of HC-22 alloy:
HC-22 alloy, also known as Hastelloy C-22, is a versatile nickel-based superalloy renowned for its exceptional resistance to a wide range of aggressive chemicals, including oxidizing acids like nitric acid, chlorides, and wet chlorine gas. This alloy derives its superior corrosion resistance from its high nickel (Ni) content (56%), along with significant chromium (Cr) (22%) and molybdenum (Mo) (13%) concentrations. These elements contribute to its ability to withstand both oxidizing and reducing environments.
HC-22 alloy exhibits excellent mechanical properties, including high tensile strength and ductility, even at elevated temperatures. Its resistance to stress-corrosion cracking and pitting makes it suitable for applications in harsh chemical processing environments, such as reactors, heat exchangers, and piping systems handling corrosive media.
The alloy is available in various forms, including sheets, plates, bars, and pipes, offering flexibility for different manufacturing and construction requirements. Its good weldability and formability allow for easy fabrication and customization to specific project needs.
HC-22 alloy is widely used across industries such as aerospace, chemical processing, pharmaceuticals, and pulp and paper manufacturing, where reliability, longevity, and performance in corrosive environments are critical requirements. Its proven track record in withstanding extreme conditions makes it a preferred choice for demanding applications where safety, durability, and efficiency are paramount.
