SS 316 / 316L Sheets and Plates Dealers and Importers

SS 316 / 316L Stainless Steel Sheets and Plates Supplier

SS 316 / 316L Stainless Steel Sheets and Plates

Petrofit Alloys And Engineering LLP is a trusted supplier, dealer and importer of SS 316 and SS 316L sheets and plates used in demanding industrial environments where corrosion resistance and durability are essential. Stainless Steel 316 is an austenitic stainless steel grade that contains molybdenum, which significantly improves resistance to corrosion in chloride and marine environments.

SS 316 and SS 316L sheets and plates are commonly used in chemical processing plants, marine systems, pharmaceutical equipment and offshore engineering structures. Compared with standard stainless steels, this grade offers improved resistance to pitting and crevice corrosion, making it suitable for aggressive industrial environments.

For welded fabrication systems requiring improved corrosion resistance after welding, engineers often choose SS 316L because of its lower carbon content. In applications where moderate corrosion resistance is sufficient, materials such as SS 304L sheets and plates are often used as an alternative depending on operating conditions.

As part of our broader stainless steel sheets and plates supply, Petrofit maintains stock of SS 316 and SS 316L materials in various thicknesses, finishes and dimensions to support fabrication companies, EPC contractors and industrial distributors worldwide.
