Hamad Fasteners, Riyadh, Saudi Arabia, is a prominent manufacturer and distributor of premium industrial fasteners, such as Hastelloy C276 fasteners. Praised for their superior corrosion resistance and mechanical properties, these fasteners are designed to operate in the most harsh chemical and high-temperature conditions. Hamad Fasteners makes sure all products adhere to international quality standards and supply to industries like chemical processing, petrochemical, and marine. With firm emphasis on reliability and durability, the company offers Hastelloy C276 fasteners that are resistant to extreme conditions and offer long-term performance.
Hastelloy C276 fasteners consist mainly of nickel (nearly 57%), molybdenum (15%), chromium (16%), and iron (balanced), with small proportions of cobalt, manganese, and silicon. This combination imparts the alloy superior pitting, crevice corrosion, and stress corrosion cracking resistance in oxidizing as well as reducing media. These fasteners possess superior tensile strength, usually around 690 MPa, and superior mechanical properties over a broad range of temperatures. The chemical resistance of the alloy to a wide range of severe chemicals qualifies it for high-performance applications.
