316N stainless steel is an austenitic stainless steel that is primarily composed of iron, chromium, nickel, and a small amount of nitrogen. It is a high-performance material that is known for its excellent strength, durability, and resistance to corrosion, particularly in chloride environments.

The “N” in 316N stands for nitrogen, which is added to the alloy in order to improve its strength and corrosion resistance. The addition of nitrogen also enhances the austenitic structure of the steel, which improves its toughness and ductility. This makes it particularly useful in applications where the material will be subjected to high stress or high temperatures.
