Stainless Steel 316 Bolts are made up of 16–18% chromium, 10–14% nickel, and 2–3% molybdenum. The inclusion of molybdenum greatly boosts corrosion resistance, especially against chlorides and industrial solvents. These bolts showcase a tensile strength ranging from 515 to 700 MPa and a yield strength between 205 and 310 MPa, along with impressive ductility, toughness, and creep resistance at high temperatures. SS 316 is non-magnetic when annealed and offers excellent weldability and formability. It retains its strength and corrosion resistance even in marine environments, brine, and harsh chemical settings, making it a top choice for both structural and fluid handling applications.
