Hastelloy C276 stud bolts use a nickel-molybdenum-chromium alloy with added tungsten and very low carbon, giving exceptional corrosion resistance. Typical composition includes high nickel (~57%), molybdenum (~16%), chromium (~15%), plus small amounts of iron, cobalt, manganese, and silicon. Mechanical properties include tensile strength around 690 MPa, yield strength near 283 MPa, and excellent ductility with roughly 40% elongation. These studs remain stable at elevated temperatures, resist pitting and stress-corrosion cracking, and ensure reliable performance in aggressive chemical, petrochemical, and marine environments.

Hastelloy C276 stud bolts are widely used in demanding environments where exceptional corrosion resistance and mechanical reliability are essential. They are commonly applied in chemical processing equipment, including reactors, heat exchangers, and pressure vessels handling acidic or chloride-rich media. In petrochemical plants, they secure piping and flanges exposed to sour gas and high-temperature operations. Power generation units use them in scrubbers and pollution-control systems due to their resistance to pitting and crevice corrosion. Additionally, marine and offshore industries rely on these studs for saltwater-exposed structures, pumps, and valves, ensuring long-term performance in highly corrosive environments.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
