Superior Corrosion and Heat Resistance

Engineered for the harshest environments, SS 317L round bar stands out with its exceptional resistance to chemicals and chlorides. Ideal for continuous and intermittent service up to 899C and 816C respectively, this alloy ensures durability and long life in marine, chemical, and petrochemical applications. Its low carbon content further reduces the risk of intergranular corrosion post-welding, making it reliable in demanding sectors.

Versatile Manufacturing and Customization

SS 317L round bars are available in diameters ranging from 4 mm up to 500 mm and can be ordered in standard 3 to 6-meter lengths or custom-cut to size. Multiple surface finish options-bright, polished, black, peeled, and pickled-cater to various fabrication and aesthetic requirements, while the bars' machinability allows for effective fabrication, ensuring compatibility with structural and mechanical applications.

FAQ's of Stainless Steel Round Bar 317L:

Q: How is Stainless Steel Round Bar 317L beneficial for chemical processing industries?

A: SS 317L round bar's high resistance to corrosion by a wide range of chemicals, thanks to its elevated chromium, nickel, and molybdenum content, makes it ideal for use in chemical processing plants. Its durability and resistance to pitting help extend equipment life and reduce maintenance costs.

Q: What welding processes are suitable for Stainless Steel Round Bar 317L?

A: This alloy supports excellent weldability by all standard methods including TIG, MIG, and arc welding without the need for post-weld heat treatment. Its low carbon content minimizes the risk of carbide precipitation, ensuring strong, corrosion-resistant welds.

Q: When should SS 317L be chosen over other stainless steel grades?

A: SS 317L is preferred when superior resistance to chemical and marine environments is required, especially where high concentrations of chlorides or reducing acids are present. Its enhanced molybdenum content provides better pitting resistance than conventional 304 or 316 grades.

Q: What is the typical process for customizing the length and diameter of SS 317L round bars?

A: Customers can order SS 317L round bars cut to specific lengths (up to 6 meters standard, or custom) and diameters (4 mm to 500 mm). Specify requirements during ordering for precision cutting and to select the preferred surface finish.

Q: Where is SS 317L round bar commonly used?

A: Common applications include construction structures, chemical and food processing equipment, pharmaceutical machinery, marine fittings, and petrochemical plants-anywhere high strength, corrosion resistance, and non-magnetic properties are needed.

Q: How does the machinability of SS 317L round bar compare to other stainless steels?

A: SS 317L offers good machinability, recommended with rigid tools and lower cutting speeds for best results. While it requires more care than some free-machining stainless steels, it responds well to standard machining processes and holds tight tolerances.

Q: What are the main benefits of using SS 317L in marine environments?

A: SS 317L's superior pitting and crevice corrosion resistance, attributable to its composition, makes it especially beneficial in saltwater or brine-rich environments. Its non-magnetic nature and robustness enhance longevity and reliability in marine applications.
