316 Stainless Steel Casting, 316L stainless steel casting

316 316L stainless steel is austenitic stainless steel. They are the second-most common material of stainless steel casting after stainless steel 304, 304L. Due to the addition of the Mo element, they are known for their superior corrosion resistance and high-temperature strength. Samely, 316 stainless steel castings and 316L stainless steel castings have the same features.

316 Stainless Steel

316 stainless steel is a popular austenitic stainless steel alloy that possesses molybdenum. ​Unlike 304 stainless steel, it has a high level of resistance to corrosion from chloride and other acids.

It increases the resistance to chemical corrosion and marine environments. 316 stainless steel is ideal for stainless steel casting components, especially for marine applications.

316L stainless steel

316L stainless steel is an extra-low carbon version of stainless steel 316. , The letter of L stands for “low.”So it is easy to remember. The distinct difference is the carbon content.

The key difference between 316 and 316L stainless steel is the carbon content. 316 has a maximum carbon content of 0.08%, 316L has a maximum carbon content of only 0.03%.

It is usually used to make the corrosion-resistant parts that contact the seawater or corrosive chemical mediums, such as valve castings, chemical equipment, outdoor lamp, medical apparatus part, marine hardware, thermal exchanger part, pipe, etc. The equivalent Grade of Stainless Steel 316 is the CF-8M of the US or 1.4408 of the German.

Applications of 316L / 316 Stainless Steel Casting

Ideal for use in harsh environments, 316/316L Stainless Steel Casting is particularly useful if exposure to salt, chlorides or chlorinated solutions is an issue. When deciding if 316 316L is the correct type of stainless steel for your project, make sure to account for both the process and the environmental factors of the application. Common industries and applications include:

  • Aerospace Structures
  • Food processing equipment
  • Brewery equipment
  • Pulp and paper processing equipment used for its resistant properties to sulfurous acids
  • Oil & petroleum refining equipment
  • Chemical transportation containers
  • Textile Industry Equipment
  • Laboratory benches & equipment
  • Boat fittings
  • Heat exchangers
  • Marine Environments
