Hastelloy C22 Bolts are made from a nickel-molybdenum-chromium alloy, with small amounts of iron, tungsten, and cobalt added in. This unique blend gives them exceptional resistance to both oxidizing and reducing agents, making them incredibly corrosion-resistant. In terms of mechanics, these bolts boast a tensile strength of about 80–120 ksi, a yield strength of 40–80 ksi, and an elongation of around 30–40%, ensuring they can handle heavy loads with ease. Hastelloy C22 maintains its structural integrity across a wide temperature range and is resistant to stress corrosion cracking, pitting, and crevice corrosion. These features make the bolts perfect for extreme chemical and industrial settings.
