Stainless Steel 317 tubing is a type of austenitic alloy that combines chromium, nickel, and molybdenum (UNS S31700) to offer exceptional resistance to corrosion, especially when it comes to sulfuric acids, chlorides, and other harsh chemical environments. The inclusion of molybdenum significantly boosts its ability to resist pitting and crevice corrosion, making it even more reliable than standard 316 stainless steel.
Typically, this alloy consists of 18–20% chromium, 11–15% nickel, 3–4% molybdenum, up to 0.08% carbon, and up to 2% manganese. Its mechanical properties are impressive, featuring a tensile strength of around 515 MPa, a yield strength of about 205 MPa, and an elongation of roughly 35%. This ensures that it maintains good ductility and strength, even when exposed to high temperatures.
