Among the austenitic stainless steels with improved corrosion resistance, 316L stainless steel 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 relatively rare type of stainless steel. Due to its high corrosion resistance, it is used in medical instruments and is sometimes called surgical stainless steel. Regarding metal allergies caused by metal ionization, 316L stainless steel is often used in jewelry as an allergy-friendly metal due to its high corrosion resistance and low ionization properties. Stainless steel 316 is used in marine sports and is seawater-resistant, while stainless steel 316L has even higher corrosion resistance.
