In order to prevent carbide precipitation, stainless steel 321 and 321H fasteners are stabilised with titanium (at least five times the carbon content) and contain 17–19% chromium and 9–12% nickel. In order to increase creep resistance and high-temperature strength, Grade 321H has a higher carbon content (0.04–0.10%). These fasteners usually have an elongation of 30–40%, a yield strength of 205 MPa, and a tensile strength of 515–620 MPa. They are ideal for extended use at temperatures up to 870°C due to their superior oxidation resistance and thermal stability, particularly in welded structures or settings with frequent heating and cooling cycles.
Applications requiring high strength and corrosion resistance under constant exposure to high temperatures make extensive use of stainless steel 321 and 321H fasteners. They are frequently found in furnace components, pressure vessels, exhaust manifolds, heat exchangers, and thermal oxidisers. While 321H is recommended for heavy-welded equipment or situations requiring increased creep strength, the 321 grade is best for general high-temperature resistance. The industries of power generation, chemical processing, petroleum refining, and aerospace all make extensive use of these fasteners. They are dependable for securing components under harsh service conditions because of their resistance to intergranular corrosion and thermal cycling.
