SAE 316L stainless steel
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 (10–12%) and molybdenum (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. 316L grade is the low carbon version of 316 stainless steel. 
It is commonly used in chemical and petrochemical industry, in food processing and pharmaceutical equipment, in potable water and wastewater treatment, in marine applications and architectural applications near the seashore or in urban areas.
