• 316L Stainless Steel Wire Mesh: 16-18% chromium, 10-14% nickel, and 2-3% molybdenum and less than 0.03% carbon.

Difference between 316 and 316L Steel Wire Mesh Corrosion Resistance

The key selling point of both 316 and 316L stainless steel is their excellent corrosion resistance, especially in chloride environments. This makes them ideal for use in marine applications, as well as in chemical processing and other industries where exposure to harsh chemicals is common.

SS 316 Stainless Steel Wire Mesh

Difference between 316 and 316L Stainless Wire Mesh

SS 316 stainless steel wire mesh is highly resistant to corrosion, particularly pitting and crevice corrosion in chloride-rich environments, the higher carbon content can lead to sensitization. This happens when the steel is exposed to temperatures between 450°C and 850°C (840°F to °F), causing the carbon to react with the chromium and form chromium carbides. This process depletes the chromium available for forming the protective oxide layer, thus reducing the material&#;s corrosion resistance in heat-affected zones.

SS 316L Stainless Steel Wire Mesh

Difference between 316 and 316L Stainless Wire Mesh

The &#;L&#; in 316L stands for &#;Low&#; carbon. With a maximum carbon content of 0.03%, 316L stainless steel is less prone to sensitization. This makes it a better option for welding applications, as it maintains its corrosion resistance in the heat-affected zones. As a result, 316L is often used in environments where welding is necessary, such as in the construction of chemical processing equipment or food handling equipment.

2. Determining Mesh Size and Opening Size

The mesh size and opening size directly impact the mesh&#;s effectiveness in applications like filtration and security. Mesh size refers to the number of openings per inch, while opening size is the actual space between the wires:

Fine Mesh (High Mesh Count): With a high number of openings per inch, fine mesh is ideal for filtering small particles in industrial applications, such as oil or water filtration.

Coarse Mesh (Low Mesh Count): Coarse mesh, with larger openings, works well for applications where larger particles need to pass through or where structural strength is required, like fencing or barriers.

Consider the intended use of the mesh to select the appropriate mesh size and opening size. Fine mesh is best for filtration, while coarser mesh serves better for structural and security purposes.

3. Selecting Wire Diameter

Wire diameter determines the strength and flexibility of the stainless-steel mesh. Thicker wires make for a stronger, more rigid mesh, ideal for heavy-duty applications, whereas thinner wires create a lighter, more flexible mesh:

Thick Diameter: Mesh with thicker wires is highly durable and used in demanding applications like fencing, window guards, or animal enclosures.

Thin Diameter: Thin wire diameter is more flexible and works well for lightweight applications, including some filtration systems and small enclosures.

The choice of wire diameter depends on the balance between the required strength and flexibility for your application. Heavy-duty needs call for a thicker wire, while fine applications can benefit from a thinner diameter.
