Stainless Steel 317 Bars are molybdenum-containing austenitic stainless steel bars that provide excellent corrosion resistance in highly aggressive environments. Supplied by Andre Stainless in Pulau Ujong, Singapore, these bars provide superior pitting and crevice corrosion resistance over SS 316 due to higher molybdenum content. SS 317 bars provide excellent strength, weldability, and resistance to creep, particularly in chemical process environments involving chlorides, sulfates, and acidic solutions. Used extensively in the pulp & paper, pharmaceutical, and marine industries, 317 bars are produced to ASTM A276 and A479 specifications and available in annealed or cold-drawn states.
SS 317 has ~18–20% chromium, ~11–15% nickel, ~3–4% molybdenum, ≤0.08% carbon, and trace amounts of manganese and silicon. It has tensile strength of ~515 MPa, yield strength ~205 MPa, elongation ~35%, and Brinell hardness ~150. The higher molybdenum enhances corrosion resistance to localized attack (pitting and crevice) and chemical attack by sulfuric, acetic, and citric acids. It is not magnetic in the annealed condition and has mechanical stability at moderately high temperatures. SS 317 also shows good formability and welding behavior and is thus highly appropriate for corrosive processing and marine conditions.
