Located in Chennai, India, Kunj Sheets and Plates is a top producer and supplier of high-performance 317L stainless steel foils. The business serves a variety of industries, including pulp and paper, chemical processing, marine, and pharmaceuticals, and is renowned for producing high-quality, corrosion-resistant products. Punj Sheets and Plates guarantees precisely engineered foils that satisfy international standards through sophisticated manufacturing facilities, strict quality control, and an emphasis on customer satisfaction. Their 317L stainless steel foils are a great option for demanding applications needing strength, durability, and dependable performance in corrosive environments because of their exceptional resistance to harsh chemicals and high moisture environments.
Stainless Steel 317L is an austenitic, low-carbon steel that contains molybdenum. It has about 18–20% chromium, 11–15% nickel, and 3–4% molybdenum. While the high molybdenum content increases resistance to pitting and crevice corrosion, the low carbon content improves weldability and resistance to intergranular corrosion. It has an approximate elongation of 35–40%, a yield strength of 205 MPa, and a tensile strength of 515 MPa. Excellent ductility, formability, and toughness are provided by the austenitic structure. Because of these characteristics, 317L foils are ideal for use in environments that are acidic, corrosive, and chloride-rich, especially when extended chemical exposure is anticipated.

Industries requiring exceptional mechanical strength and corrosion resistance frequently use stainless steel 317L foils. They are perfect for lining heat exchangers, tanks, and reactors exposed to harsh chemicals and acids in petrochemical and chemical processing. They serve as anti-corrosion barriers, insulation, and protective wraps in maritime settings. 317L foils are used in the pulp and paper industries for digesters and bleach plants. They are also appropriate for use in power generation, pharmaceuticals, and food processing. 317L foils are great for custom-fabricated parts that operate in harsh or corrosive environments because of their flexibility, weldability, and resistance to corrosion.
