With an emphasis on quality and accuracy, the company provides Hastelloy C22 fasteners that offer long-term reliability and safety in the most extreme applications.
The Hastelloy C22 fasteners are made of a majority of nickel (about 56%), supplemented with large percentages of chromium (20–22.5%), molybdenum (12.5–14.5%), and iron, along with small percentages of cobalt, tungsten, and others. This special alloy has superb resistance to a broad spectrum of corrosive media, such as oxidizing and reducing agents. Such fasteners have high tensile strength, usually ranging from 690 MPa, and possess superior mechanical stability even at higher temperatures. Their structure makes them well suited in environments where pitting, crevice corrosion, and stress corrosion cracking are issues.
