Renowned for their material traceability, dimensional accuracy, and consistent quality, Lina Fasteners offers both standard and custom Hastelloy Screws that are built to perform reliably in extreme temperatures, high pressures, and highly corrosive environments around the globe.
Hastelloy Screws are crafted from nickel-based superalloys that include significant amounts of chromium, molybdenum, and iron, with variations based on the specific grade. Chromium offers excellent resistance to oxidation, while molybdenum boosts resistance to pitting and crevice corrosion. On the mechanical side, Hastelloy screws showcase high tensile strength, remarkable creep resistance, and impressive fatigue performance even at elevated temperatures. They maintain their toughness in low temperatures, resist stress corrosion cracking, and keep their mechanical stability during thermal cycling, making them ideal for environments with extreme pressure, heat, and aggressive chemicals.
