316/316L is the most used austenitic stainless steel in the chemical process industry. The higher nickel and molybdenum content in this grade allows it to demonstrate better overall corrosion resistant properties than 304/304L, especially with regard to pitting and crevice corrosion in chloride environments. It also offer higher creep, stress rupture and tensile strength in elevated temperature. Type 316L is an extra-lower carbon version of type 316 that eliminates harmful carbide precipitation due to welding. Generally all Merinox tubing is dual- certified to meet both 316 and 316L.
