A Comparison of 304 and 316 Stainless Steel Filters: Understanding the Differences and Applications

When it comes to stainless steel filters, it's important to differentiate between 304 stainless steel mesh and 316 stainless steel mesh based on their unique properties. In this article, we explore the advantages and applications of each type.

316 Stainless Steel Mesh:

Known for its exceptional corrosion resistance, 316 stainless steel mesh contains 18% chromium, 12% nickel, and 2.5% molybdenum. The addition of molybdenum enhances its ability to withstand harsh conditions, making it less prone to corrosion in saltwater, sulfur water, and brine. It also exhibits excellent atmospheric corrosion resistance and high-temperature strength. Notably, 316 stainless steel filters are highly resistant to erosion from ocean environments and corrosive industrial atmospheres. They are particularly suitable for applications in the production of pulp and paper.

304 Stainless Steel Mesh:

While also offering good high-temperature resistance, 304 stainless steel mesh boasts excellent corrosion resistance and resistance to intergranular corrosion. In experiments, it has demonstrated strong resistance to oxidizing acids, such as nitric acid below boiling temperature with a concentration of ≤ 65%. Additionally, it exhibits good corrosion resistance to alkaline solutions and most organic and inorganic acids.

Applications of 316 Stainless Steel Mesh:

316 stainless steel mesh finds extensive use in screening and filtration applications, especially in acidic and alkaline environments. It is widely employed in industries such as mining, chemicals, food processing, and pharmaceuticals.

Both 304 and 316 stainless steel filters have their own advantages and are suitable for different scenarios. By understanding their unique properties, industries can select the appropriate stainless steel mesh for their specific needs, ensuring optimal filtration performance and corrosion resistance.
