What is 316L Stainless Steel? 316L, also known by A4 grade stainless or marine-grade stainless steel is the second most widely used austenitic steel after 304/A2 Stainless steel. The main alloy composition is iron, which includes chromium (16-18%) as well as nickel (10-12%) and mollybdenum (2-4%). There’s also a small amount ( 1%) of silicon, sulfur, phosphorus and phosphorus.

316L is often used in the chemical, petrochemical and food processing industries, food equipment, pharmaceutical devices, medical devices and drinking water.

316L vs.316L
Both the 316L and316L stainless steel alloys have marine-grade properties. The only difference is the lower carbon content in 316L. The carbon content cannot exceed 0.03% in order to comply with 316L stainless-steel requirements. This reduces the chance of carbon deposition making it an excellent choice for welding. It also ensures maximum corrosion resistance.

316 stainless steel is medium in carbon and has a moderate molybdenum percentage of between 2 and 3 percent. This improves its resistance to corrosion and acidic elements as well as high temperatures.
Both materials exhibit excellent ductility which allows them to perform well in bending and stretching.

Should I use stainless steel 316L or316?
Consider the following:
Corrosion resistance
The best choice for high temperature and corrosion applications is 316L. 316L’s carbon content is lower than 316’s, so it is better at resisting intergranular corrosion. This means that 316 stainless will not rot.

The prices of 316L and316L stainless steel are roughly equal.

Magnet properties
The magnetism of 316 stainless-steel is low. Most varieties of stainless steel, including 316, are austenitic (or non-magnetic) unlike ferromagnetic stainless steels.

Some 316 stainless-steel products can be cold-formed and welded, where the crystal structure of austenite becomes ferromagnetic martensite. It is easier for 316L to attain a certain degree magnetism.

Both types of stainless can be used for different purposes. Due to its strength, corrosion resistance, and pitting resistance, 316 is the most popular type of stainless steel. Because it can withstand welding, and corrosive chemical, 316L has a lot of appeal in photographic and pharmaceutical equipment.
