The Mumbai, India-based Fasteners Mart specializes in manufacturing and exporting high-performance industrial fasteners known for accuracy, long life, and quality assurance. Hastelloy C276 Fasteners, one of their high-end products, are fabricated from corrosion-resistant Nickel-Molybdenum-Chromium alloy (UNS N10276). Hastelloy C276 Fasteners are available in different shapes like bolts, nuts, screws, washers, and studs, designed with high strength and chemical resistance. Well-suited for extreme conditions, Hastelloy C276 Fasteners are used extensively in a wide range of industries where reliability and long service life are essential.
Hastelloy C276 Fasteners consist mainly of Nickel (57%), Molybdenum (16%), Chromium (15.5%), Iron (5%), and traces of Tungsten and Cobalt. They possess good mechanical properties with a tensile strength of approximately 760 MPa and a yield strength of 300 MPa, and 40–45% elongation. Physically, Hastelloy C276 Fasteners possess a density of 8.89 g/cm³ and a melting point of 1325°C to 1370°C. These properties render them extremely resistant to pitting, crevice corrosion, and stress corrosion cracking in hostile chemical environments.
