Among the austenitic stainless steels with improved corrosion resistance, stainless steel 316L is particularly corrosion-resistant. 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 relatively low distribution. Due to its high corrosion resistance, it is used in medical instruments and is sometimes called surgical stainless steel. Metal allergies are caused by the ionization of metals, but due to its high corrosion resistance = low ionization properties, it is 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.
