317L Stainless Steel | Stainless Steel Supply

317L is an austenitic stainless steel which provides higher levels of chromium, nickel and molybdenum than other stainless steels, thus enhancing its corrosion resistance. The “L” in 317L signifies a lower carbon content compared to normal 317 steel, reducing the chances of sensitization and maintaining corrosion-resistant properties. This type of steel is commonly used in industries involving chemical and petrochemical processing, pulp & paper manufacturing, food production and pharmaceuticals where durability at high temperatures is essential. Due to its superior resistance to corrosive substances and elevated temperatures it can be found in cookers and sterilizers.
