Best Stainless now stocks Stainless Steel 317 and 317L, enhanced with higher Chromium-Nickel-Molybdenum for improved properties.
- Superior corrosion resistance over 316/316L stainless steel.
- Increased molybdenum content aids in pitting and chemical corrosion resistance.
- The 317L variant's reduced carbon content ensures better weldability and formability.
- Non-magnetic in the annealed state and not hardenable by heat treatment.
- Ideal for demanding environmental conditions.
Please contact Best Stainless for more information about how 317 SS can best suit your specific application.
