Hastelloy fasteners are highly versatile components essential in industries requiring superior corrosion resistance and mechanical strength. Manufactured from premium Nickel-based alloys like Alloy C276, these fasteners include bolts, nuts, screws, washers, and threaded rods designed to perform in extreme environments. The advanced composition of Hastelloy C276—containing approximately 55% nickel, 15% molybdenum, 14.5% chromium, tungsten, and iron—ensures excellent resistance to oxidizing and reducing agents, making them indispensable in chemical processing, marine, and aerospace sectors.
Hastelloy fasteners offer impressive tensile strength ranging from 850MPa to 1600MPa, catering to high-stress applications. They can be annealed for enhanced flexibility or spring-tempered for maximum strength. With a melting range of 1325°C to 1370°C, they are reliable under high-temperature conditions. Manufactured to adhere to strict standards like ASTM B574 and ASME B18.16.6, these fasteners are available in a broad size range, including diameters from M02 to M160 and lengths from 3mm to 300mm, ensuring compatibility with diverse applications.
