316L grade is the low Carbon (C) version of 316 grade. They are within austenitic stainless steels group.

Due to its Molybdenum (Mo) content, 316 grade is resistant to non-oxidising acids and other corrosive environments such as salt and toxic gas. Therefore it is preferred in seaside environments.

Molybdenum (Mo) gives 316L grade better corrosion resistance. Intergranular corrosion resistance is also better than 304L grade.

This grade is not magnetic in annealed condition.

316L grade is heat resistant up to 700°C. In the continuous heat higher than this degree, 316L grade is not recommended. Weldability is very good for 316L grade, and annealing is not required after welding.

Machinability is average with the right tools, and it is more difficult than 304 grade.

Cold formability and ductility is good for 316L. This grade is polishable.

Available forms: Round Bars, Flat Bars, Hexagon Bars, Square Bars, Angles, Wires, Special Profiles, Coils, Sheets, Strips, Welded Tubes, Seamless Tubes, Profiles, Fittings.
