442 Stainless Steel The ferritic stainless steel alloy used to make nuts contains about 12.5% chromium and 1% molybdenum. At higher temperatures, this composition improves the material’s resistance to oxidation, scaling, and corrosion. These nuts are perfect for high-temperature applications because of their good hardness, moderate tensile strength, and exceptional thermal stability. Among their mechanical characteristics are steady performance under heat cycling and strong creep resistance. The structure of the alloy adds to the nut’s resilience to deformation and toughness, providing long-term durability in harsh and temperature-changing conditions.
