316L Stainless Steel Differs From 316 Stainless Steel By yaang.com

Grade 316L Stainless Steel is very similar to 316 stainless steel. It is still considered a molybdemum-bearing grade and has properties that make it highly resistant to corrosive degradation. grade 316L stainless steel differs from 316 in that contain lower levels of carbon. The decreased level of carbon in this stainless steel makes this grade immune from sensitisation or grain boundary carbide precipitation. Because of this unique property, Grade 316L Stainless Steel tends to be commonly used in heavy gauge welding situations.  Additionally the lower carbon levels make this grade easier to machine. Like 316 stainless steel, 316L Stainless Steel because of its austenitic structure is extremely tough, even in the most extreme of temperatures.

Common Trade Names

316L Stainless, 316L Stainless Steel


  • Grade 316L Stainless Steel is easily welded by all commercial processes. If forging or hammer welding it is recommended to anneal after these processes to help avoid unwarranted corrosion.
  • Not hardenable by heat treatment, however often cold working the alloy has proven to increase hardness and tensile strength.
  • Sometimes know by industry professionals as marine grade stainless for its uncanny ability to resist pitting corrosion.


Grade 316L Stainless Steel is one of the more common austenitic stainless steels. Because of its outstanding toughness against corrosion you can typical find Grade 316L Stainless Steel used in the following applications: Shipbuilding, Nuclear power, Marine engineering, Petroleum, Chemical, Mining,Sewage treatment, Natural gas and Pressure vessels and other industries.
