Material Specification of 430 Stainless Steel Wire Mesh
1.Material
430 stainless steel wire mesh is manufactured from ferritic stainless steel grade 430, primarily alloyed with chromium and containing little or no nickel. It offers good corrosion resistance, oxidation resistance, and heat resistance. Compared with austenitic stainless steels, it provides higher thermal conductivity and a lower thermal expansion coefficient, making it suitable for moderate corrosive and temperature-variable environments at a lower cost.
2.Mesh Count
The common mesh count range for 430 stainless steel wire mesh is 2 mesh to 40 mesh.
2-10 mesh:Large openings and high permeability, commonly used for protection, ventilation, screening, and structural support
10-20 mesh:Medium openings, suitable for coarse filtration, separation, and industrial screening
20-40 mesh:Relatively finer mesh range, used for general filtration, particle separation, and material screening
3.Wire Diameter
The typical wire diameter range for 2–40 mesh 430 stainless steel wire mesh is 0.25 mm to 3.0 mm, depending on the mesh size and strength requirements.
0.25-0.50 mm:Used for higher mesh counts with moderate filtration precision
0.50-1.50 mm:Common wire diameter range for standard industrial screening applications
1.50-3.00 mm:Heavy wire diameter for low mesh counts requiring high strength and durability
4.Opening Size
The opening size of 430 stainless steel wire mesh in the 2–40 mesh range generally falls between 0.4 mm and 10.0 mm.
Larger opening sizes allow higher airflow and material throughput, while smaller openings provide more controlled screening and filtration performance.
5.Open Area
The open area of 2–40 mesh 430 stainless steel wire mesh typically ranges from 35% to 75%, depending on wire diameter and mesh configuration.Higher open area designs improve airflow and flow efficiency, while lower open area designs focus on improved screening accuracy and mechanical stability.
6.Weight
The weight per square meter of 430 stainless steel wire mesh within the 2–40 mesh range usually ranges from 1.0 to 15 kg/m².Lower mesh counts with thicker wires result in heavier mesh panels, while higher mesh counts with finer wires produce lighter mesh structures.

Demonstrates good heat resistance and can operate at elevated temperatures without excessive oxidation or surface scaling.
Offers good formability and ductility, allowing the wire mesh to be fabricated into various shapes and configurations while maintaining structural stability.
Features a low thermal expansion rate, helping the mesh maintain dimensional stability under thermal cycling or temperature fluctuations.
Possesses solid mechanical strength and durability, making it suitable for continuous or moderately demanding service conditions.
Cost-effective compared with austenitic stainless steels, providing a balanced solution between performance and material cost.
Applications of 430 Stainless Steel Wire Mesh
Architectural decoration mesh and protective structures
Industrial ventilation screens and equipment guards
Heat-resistant screens for burners and thermal components
Protective mesh for household appliances and equipment parts
Coarse filtration and screening applications
Safety guards for machinery and industrial equipment
Packaging of 430 Stainless Steel Wire Mesh
430 stainless steel wire mesh is commonly packed using moisture-proof and pressure-resistant industrial packaging methods to ensure integrity during transportation and storage. The mesh is first wrapped with moisture-proof paper or plastic film as inner packing, then packed in rolls or cut into sheets according to specifications. The outer layer is usually reinforced with kraft paper, woven bags, or plastic film. For export or long-distance shipping, wooden cases or pallets are often used to prevent deformation and surface damage, with clear labels indicating material, mesh count, wire diameter, and size for easy identification and storage.
