Hamad Fasteners is a reputable manufacturer and supplier of specialized industrial fasteners located in Riyadh, Saudi Arabia. We provide high-performance fastening solutions tailored for industries that face harsh and corrosive conditions. One of our standout products, the Hastelloy C276 Bolts, is designed to offer remarkable resistance to chemical attacks and exceptional mechanical strength. These bolts are perfect for critical applications in sectors like chemical processing, power generation, marine, and pollution control. At Hamad Fasteners, we guarantee that every Hastelloy C276 Bolt adheres to global quality standards, ensuring reliable performance even in the toughest operational environments.
Hastelloy C276 Bolts are made up of nickel (about 57%), molybdenum (15–17%), chromium (14.5–16.5%), along with trace amounts of iron, tungsten, and cobalt. This unique blend gives them outstanding resistance to strong oxidizing and reducing agents, such as hydrochloric acid, sulfuric acid, and chlorine-containing substances. These bolts boast a high tensile strength of around 750–850 MPa and maintain their structural integrity under both high temperatures and pressures. Hastelloy C276 is resistant to pitting, crevice corrosion, and stress corrosion cracking, making it the go-to material for environments where aggressive chemicals and extreme conditions are a regular occurrence.
