In Barsham Nickel Alloys, headquartered in Doha, Qatar, we take pride in being a leading manufacturer and supplier of Hastelloy fasteners. Known for their excellent resistance to corrosion and elevated temperatures, our Hastelloy fasteners are designed to fulfill the tough requirements of aerospace, chemical processing, and marine sectors. In maintaining a focus on quality and accuracy, we promise that our product offers consistent performance in the harshest applications. Join with us for excellence and durability that Hastelloy fasteners of the highest class can offer.
Hastelloy fasteners consist of a nickel-chromium-molybdenum alloy, with the major content being 57% nickel, 16% molybdenum, 15% chromium, while iron and tungsten occur in trace amounts. The special composition gives the fasteners superior corrosion resistance, especially in aggressive chemical environments and elevated temperatures. The fasteners possess outstanding mechanical properties such as tensile strength of about 1,300 MPa, superb fatigue strength, as well as high stress corrosion cracking resistance. These properties render Hastelloy fasteners suitable for application in industries such as chemical processing, aerospace, and power generation, where strength and reliability under extreme conditions are crucial.
