316L and 316 Stainless Steel Housings: What's the difference?

Stainless steel are a popular choice for a wide variety of industrial piping applications. The 300-series stainless steel formulas are the most preferred option, as they have the right mix of strength and weldability, and are generally an economical choice. They are also non-magnetic and corrosion resistant. This property is the reason why they are used in industry and domestic situations.

Graver manufactures liquid filtration housing systems using both 316L and 316 stainless steel, but which one is suitable for your application?

The Difference

316L and 316 stainless steel are almost identical, with the only difference being their carbon content. The "L" in 316L indicates a low carbon content. Since 316L contains less carbon than 316, it has better intergranular corrosion resistance, meaning its welds won't decay, unlike with 316 stainless steel. The 316L also has better corrosion resistance compared to the 316, and doesn't require post-weld annealing (a process that strengthens the quality and hardness of the material). 316L is the superior choice for high corrosion and high temperature applications.

Common Uses

Some industrial processes require stringent cleanliness and purity, such as in the case of pharmaceutical processes, or semiconductor manufacturing. These industries will require a filtration housing made of 316L stainless steel.

While other applications also have cleanliness guidelines and standards, they are not as strict as the afore mentioned industries. Therefore, a 316 stainless steel housing is sufficient for industries such as F&B, cosmetics, coatings, and more.

Graver's 316L GHP Series Filter Housings

Our GHP housings are constructed using 316L stainless steel and engineered using 3A standards for filtration applications requiring high purity production streams. The internal surface is acid washed for a consistent, easy-care finish. Typical applications incluide:

  • Ultrapure Chemicals

  • Ultrapure Water

  • Wine/Beer

  • Bottled Water

  • Vaccines

  • Diagnostics

  • Edible Oils

  • Tank Vents
