Stainless Steel 321 and 321H Nuts are crafted from an austenitic stainless steel alloy that includes chromium, nickel, and titanium. The addition of titanium helps prevent carbide precipitation, enhancing resistance to intergranular corrosion when exposed to high temperatures. Grade 321H features a higher carbon content, which boosts its tensile strength and creep resistance at elevated temperatures. Mechanically, these nuts demonstrate impressive tensile and yield strength, outstanding toughness, and stability under thermal stress. Their ability to resist oxidation and thermal fatigue makes them perfect for demanding applications that require long-lasting reliability and performance.
