Inconel Alloy X-750 / N 07750 / 2.4669 Nut For Versatile Applications
Inconel Alloy X-750 /N 07750/2.4669 Nut Retains Good Mechanical Properties At Cryogenic Levels For Versatile Applications
Inconel Alloy X-750 (N07750 / 2.4669) nuts are high-strength, corrosion-resistant fasteners made from a nickel-chromium alloy. They offer excellent performance in extreme temperatures, oxidation resistance, and high tensile strength. Commonly used in aerospace, nuclear, and high-temperature applications, these nuts maintain mechanical properties up to 1300°F (704°C). They also exhibit good creep resistance and stress rupture strength, making them ideal for demanding environments.
