Hamad Fasteners, located in Riyadh, Saudi Arabia, stands out as a trusted manufacturer and supplier of top-notch industrial fasteners designed to thrive in harsh chemical and corrosive environments. Our Hastelloy Nuts are crafted to deliver exceptional corrosion resistance and mechanical strength, making them perfect for demanding industrial settings like chemical processing, marine operations, and pollution control systems. Built to meet international quality standards, these nuts ensure outstanding performance even in highly acidic and oxidizing conditions, providing long-lasting reliability and safety.
Typically, Hastelloy Nuts are made from high-performance nickel-based alloys such as Hastelloy C22, C276, or X, featuring a composition rich in nickel (over 50%), molybdenum, chromium, and iron. These materials offer remarkable resistance to strong oxidizers, chlorides, and various acids, including sulfuric, nitric, and hydrochloric. Depending on the specific grade, Hastelloy nuts can achieve tensile strengths ranging from 690 to 900 MPa, maintaining their strength and corrosion resistance even in high-temperature and highly acidic environments. They are also resistant to pitting, crevice corrosion, and stress corrosion cracking.
