Among the austenitic stainless steels with improved corrosion resistance, stainless steel 316L is particularly excellent in corrosion resistance. The "L" in 316L stands for "Low Carbon," indicating a low carbon content, which reduces corrosion resistance. It is also a special type of stainless steel with a relatively small distribution volume. Due to its high corrosion resistance, it is used in medical instruments and is sometimes called surgical stainless steel. Regarding metal allergies associated with metal ionization, due to its high corrosion resistance = low ionization properties, it is also often used in jewelry as a metal that is compatible with metal allergies. Stainless steel 316 is used for marine sports and is seawater-resistant, and stainless steel 316L has even higher corrosion resistance.
