SAE 316L grade stainless steel is the second most common austenitic stainless steel after 304. Its primary alloying constituents after iron, are chromium (between 16-18%), nickel (between 10-12%) and molybdenum (between 2-3%). The addition of molybdenum provides greater corrosion resistance than 304, with respect to localized corrosive attack by chlorides and to general corrosion by reducing acids, such as sulphuric acid.[1]

It is commonly used in chemical and petrochemical industry, in food processing and pharmaceutical equipment, in potable water[2][3] and wastewater treatment[4], in marine applications[5] and architectural applications near the seashore or in urban areas.[6][7]

316L stainless steel is also used to make the case of the Samsung Gear S3 smartwatch.
