The chemical composition of stainless steel 316L is generally composed of 16 to 18% chromium, 10 to 14% nickel, 2 to 3% molybdenum, and a small percentage of carbon(≤0.030%), adding molybdenum to stainless steel 316L increases its corrosion resistance compared to other grades of stainless steel.

Due to 316L’s excellent properties, 316L is expended in some other grades for various applications, developing other stainless steels by adding different chemical elements, such as adding a small amount of Ti derived after 316Ti, which offers better resistance to intergranular corrosion, adding a small amount of N derived from 316N, increasing the content of Ni and Mo derived 317.

316L/4404 has excellent corrosion resistance in solutions of many halogen-free organic and inorganic compounds over a wide temperature and concentration range.
With good oxidation resistance in intermittent service to 870 °C and in continuous service to 925 °C, Grade 316L stainless steel is more resistant to carbide precipitation.
Good oxidation resistance in intermittent service to 870 °C and in continuous service to 925 °C. Continuous use of 316 in the 425-860 °C range is not recommended if subsequent aqueous corrosion resistance is important. Grade 316L is more resistant to carbide precipitation and can be used in the above temperature range. Grade 316H has higher strength at elevated temperatures and is sometimes used for structural and pressure-containing applications at temperatures above about 500 °C.
Excellent weldability by all standard fusion methods, both with and without filler metals, Heavy welded sections in Grade 316 require post-weld annealing for maximum corrosion resistance, this is not required for Grade 316L.
316L annealing temperature range is 1900 to 2100°F (1038 to 1149°C), cannot be hardened by heat treatment, It can be hardened by cold working.
316L stainless steel tends to work harden if machined too quickly. For this reason, low speeds and constant feed rates are recommended.
316L stainless steel is also easier to machine compared to 316 stainless steel due to its lower carbon content.
316L is very similar to 316 in almost every aspect. They are both durable, corrosion-resistant, and a good choice for high-stress applications, in practice, dual-certified grade 316/316L is often required.
However, the “L” designation means 316L steel has less carbon than 316 steel, it is less susceptible to sensitization, a condition caused when carbon combines with chromium around the grain boundaries, depleting the grain boundary areas of chromium during the welding process, though it can be resisted via annealing.
