Boikanyo Sheets and Plates, located in Cape Town, South Africa, is a reliable manufacturer and supplier of stainless steel 317L foils. They focus on delivering top-notch products that are designed for outstanding corrosion resistance, durability, and mechanical performance. Using advanced cold rolling and annealing techniques, the company produces precision-engineered 317L foils that boast uniform thickness, a smooth surface finish, and excellent dimensional accuracy. These foils are perfect for use in industries like chemical processing, pharmaceuticals, marine, and food, where materials need to withstand harsh chemicals and high humidity while ensuring a long service life.
Stainless steel 317L foils are low-carbon austenitic stainless steels that contain 18–20% chromium, 11–14% nickel, and 3–4% molybdenum. The molybdenum addition enhances their resistance to pitting, crevice corrosion, and oxidizing environments, making them superior to 316L. With a tensile strength ranging from 485–620 MPa and a yield strength of 170–310 MPa, these foils also offer excellent ductility, weldability, and formability. Their low carbon content helps prevent sensitization during welding, which is crucial for high-integrity applications in corrosive settings.
