304 vs 316 Stainless Steel Overview
304 Stainless Steel Mesh
304 stainless steel mesh is a metal screening and filtration material woven from 18Cr-8Ni austenitic 304 stainless steel wire using techniques such as plain weave, twill weave, crimping, and welding. It is the most versatile and widely used type of stainless steel mesh on the market, manufactured in accordance with the GB 5330-2003 national standard. It offers good corrosion resistance in dry environments and serves as a cost-effective solution.
316 Stainless Steel Mesh
316 stainless steel mesh is a high-end, corrosion-resistant woven metal filter mesh; compared to the 304 grade, it contains added molybdenum and higher levels of chromium and nickel. Like the 304 variant, it is available in plain weave, twill weave, crimped, and welded configurations, covering a full range of specifications from 4 to 600 mesh. It offers far superior resistance to rust and salt corrosion compared to 304, making it suitable for applications involving seawater, chemicals, pharmaceuticals, and high-salinity environments, though it comes at a higher overall cost.

Common Problems Caused by Wrong Mesh Selection
Corrosion & Short Service Life
Using 304 in chloride/salt environments leads to pitting rust, wire breakage and mesh damage, greatly shortening service life.
Unqualified Filtration Effect
Corroded mesh causes uneven holes, powder leakage and impurity penetration, resulting in unstable filtration and screening accuracy.
Mesh Blocking & Material Waste
Rust deposits and corrosion residues block mesh holes, reduce screening efficiency and cause material accumulation and waste.
Increased Operating Cost
Frequent mesh replacement increases material costs and causes repeated equipment shutdowns, reducing overall production efficiency.
Product Quality Risk
Rust and metal debris may mix into finished products, causing contamination, especially for food, pharmaceutical and chemical production.
