Stainless Steel 317/317L Flanges refer to a specific type of flange made from the alloys 317 and 317L stainless steel. Stainless steel is a versatile and corrosion-resistant material widely used in various industries for its durability and performance in challenging environments. The numbers 317 and 317L denote different grades within the stainless steel alloy family.
Stainless Steel 317 is a higher chromium, nickel, and molybdenum version of standard austenitic stainless steels. The increased alloy content provides enhanced corrosion resistance, particularly in acidic and corrosive environments. Stainless Steel 317 is often used in applications where high corrosion resistance is crucial, such as in chemical processing, pulp and paper industries, and in the manufacturing of textiles.
Stainless Steel 317L is a low-carbon version of Stainless Steel 317. The reduced carbon content minimizes the risk of sensitization, a phenomenon where the material is prone to corrosion when exposed to certain temperatures. Stainless Steel 317L is ideal for applications where welding is involved, as it minimizes the formation of carbide precipitation around the weld areas.
