316L

Product Description:

316L stainless steel is a low-carbon version of 316 stainless steel, widely known for its excellent resistance to corrosion, particularly in chloride-rich and acidic environments. The “L” in 316L stands for “Low Carbon,” which minimizes the risk of carbide precipitation during welding, thereby improving resistance to intergranular corrosion. It is an austenitic stainless steel, meaning it has a face-centered cubic (FCC) structure, giving it superior toughness, formability, and weldability. 316L is commonly used in industries that require resistance to harsh environments, such as in the chemical, pharmaceutical, marine, and medical sectors.
