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. Iron’s main alloy components are chromium (16-18%), nickel (10-12%), and molybdenum (2-4%). There is also a small amount ( 1%) of silicon, sulfur, and phosphorus.

316L is often used in the chemical, petrochemical, food processing, pharmaceutical, medical equipment, drinking water and wastewater treatment, as well as in urban areas.

Both the 316L and316L stainless steel alloys can be used to make marine-grade steels. The only difference is the lower carbon content in 316L. To comply with 316L requirements, carbon must not exceed 0.03%. 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 content with a moderate molybdenum percentage of between 2 and 3. 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 applications and high corrosion is 316L. 316L’s carbon content is lower than 316’s, so it has better resistance to intergranular corrosion. This means that 316 stainless will not rot.

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

Magnet properties
The magnetism of 316 stainless-steel is low. Contrary to ferromagnetic stainless steels, many stainless steels (including 316), can be used as austenitic steels.

Some 316 stainless-steel products can be cold formed, welded and transformed into ferromagnetic martensite. A certain amount of magnetism can be achieved with 316L stainless steel.

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.
