When it comes to composition, Stainless Steel 321 / 321H Nuts are primarily made of iron, featuring 17–19% chromium and 9–12% nickel, with titanium added to fend off intergranular corrosion. The 321H variant has a higher carbon content (0.04–0.10%) to boost its strength at elevated temperatures. These nuts deliver impressive tensile strength ranging from 515–750 MPa and yield strength between 205–275 MPa, with an elongation of about 40%. Their Brinell hardness falls between 150–220 HB. Both grades shine in oxidation resistance, holding up to 900°C, making them ideal for thermal and pressure-bearing applications in harsh chemical environments.
