Stainless Steel 321 Bolts are titanium-stabilized austenitic stainless steel fasteners known for their impressive resistance to intergranular corrosion. Typically, their chemical makeup includes 17–19% chromium, 9–12% nickel, and trace amounts of titanium (≥5xC), which improves weldability and helps prevent carbide precipitation. These bolts boast good mechanical strength, with a tensile strength of about 515 MPa and a yield strength of 205 MPa, along with a hardness rating of roughly 217 HB. The alloy performs well in temperatures up to 870°C, making it suitable for applications that involve thermal cycling and exposure to oxidation.
