317/317L Stainless Steel Bar

Best Stainless now stocks 317 stainless steel round bar and 317L stainless steel round bar, enhanced with higher chromium, nickel, and molybdenum content for improved properties. These materials offer superior corrosion resistance compared to 316 and 316L stainless steel, making them ideal for demanding applications.

The increased molybdenum content in 317 stainless steel round bar enhances resistance to pitting and chemical corrosion. The 317L variant features reduced carbon content, ensuring better weldability and formability. Both grades are non-magnetic in the annealed state and are not hardenable by heat treatment, making them suitable for various environmental conditions.

Applications and Features

317 and 317L stainless steel round bars are commonly used in:

• Chemical process vessels
• Condensers in power generation
• Pulp and paper manufacturing

These bars exhibit excellent corrosion resistance and strength, improving resistance to general and localized corrosion compared to 316 and 316L stainless steels.

Product Availability

Our stainless steel bar stock lengths range from the industry standard of 12 feet to 28 feet long. For projects requiring longer lengths, we offer inventory options from 20 to 28 feet R/L.
