Stainless Steel 317 is a molybdenum-bearing austenitic stainless steel alloy that typically contains around 18–20% chromium, 11–15% nickel, 3–4% molybdenum, and ≤0.08% carbon. This unique blend enhances its corrosion resistance, especially against chlorides and acidic conditions. SS 317 bolts boast a tensile strength ranging from 515–620 MPa, a yield strength of 205–275 MPa, and an elongation of about 35–45%, with hardness levels between 80 and 90 HRB. These impressive mechanical properties, along with exceptional chemical resistance, make 317 bolts ideal for demanding applications that require both strength and long-lasting protection against corrosion.
