317 stainless steel has 18–20% chromium, 11–15% nickel, and 3–4% molybdenum, with a maximum carbon content of 0.08%. Grade 317L reduces carbon to a maximum of 0.03%. This composition enhances resistance to chlorides, which helps reduce pitting and crevice corrosion. Mechanical properties include tensile strength around 515 MPa, yield strength around 205 MPa, and elongation of at least 40%. These grades offer good ductility, toughness, and protection against corrosion in aggressive chemical environments.
