Stainless Steel 317L ( S31703 / AISI 317L ) is the low-carbon derivative of Stainless Steel SS317 ( S31700 ). The metal maintains its high strength and strong corrosion resistance; however, the carbon content does have several effects. SUS317L has greater srength under welding; its products are stronger.
Like SUS 317, stainless steel 317L does not respond or harden from heat treatments. When hot working, the metal should be heated ideally within the range of 2100-2300°F.
Dropping below 1700°F will cause the metal to be unresponsive. For these reasons, SS317L is effective in high temperature areas that experience high rates of chemical corrosion, creep, and stress-to-rupture.
Materal SS317L is commonly utilized in chemical environments. It has shown itself to be effective in conditions where acids are present, such as acidic chloride. The metal is resistant to corrosion from such substances. As such, it is common to find 317L stainless steel in equipment used in pulp and paper mills. The acidic environment requires a strength, corrosion resistant metal.
It is possible for Stainless Steel Grades SS317 and SS317L to become dually certified.

Resistance to Corrosion: Stainless Steel Types SUS 316, SUS 316L, SUS 317 and SUS 317L are more resistant to atmospheric and other mild types of corrosion than Stainless Steel Types SUS302, SUS304 and SUS304L. In general, media that do not corrode Types SUS 302, SS304, and SS304L Stainless Steel, will not attack these molybdenum-containing grades. One known exception is highly oxidizing acids such as nitric acid to which the molybdenum-bearing stainless steels are less resistant.
Features of Stainless Steel 317L
- Excellent corrosion resistance
- Higher creep, stress-to-rupture and tensile strength at elevated temperature
- Able to maintain clean surfaces
