SS 317 / 317L Sheets and Plates Dealers and Importers

SS 317 / 317L Stainless Steel Sheets and Plates Supplier

SS 317/317L Stainless Steel Sheets and Plates

Petrofit Alloys And Engineering LLP is a trusted supplier, dealer and importer of SS 317 and SS 317L sheets and plates used in highly corrosive industrial environments. Stainless Steel 317 is an austenitic stainless steel grade that contains a higher percentage of molybdenum compared to SS 316, which significantly improves resistance to chemical corrosion and pitting.

SS 317 and SS 317L sheets and plates are commonly used in chemical processing plants, petrochemical facilities, pollution control systems and pharmaceutical manufacturing equipment. The increased molybdenum content enhances resistance to aggressive chemical exposure, making this material suitable for demanding industrial conditions.

For high-temperature environments where oxidation resistance is critical, materials such as SS 310 / 310S sheets and plates are often used. However, in applications involving strong chemical exposure and corrosive media, SS 317 and SS 317L provide improved corrosion resistance.

As part of our broader stainless steel sheets and plates supply, Petrofit maintains ready stock of SS 317 and SS 317L materials in multiple thickness ranges, finishes and plate dimensions to support fabrication companies, EPC contractors and industrial distributors worldwide.
