Micron Stainless Steel Mesh

Micron stainless steel mesh is a metallic screen whose opening size is specified in micrometres (µm). It is produced from austenitic stainless steel grades such as 304, 316L, or 904L, chosen for their corrosion resistance and mechanical stability in aggressive environments.

Technical Specifications

Parameter	Typical Range
Mesh Opening (µm)	5 – 250
Wire Diameter (mm)	0.02 – 0.5
Open Area (%)	10 – 70
Tensile Strength (MPa)	≥ 500 (depending on grade)
Temperature Limit (°C)	Up to 400 (continuous)

Material Options

• AISI 304 – good general corrosion resistance, suitable for food and beverage processing.
• AISI 316L – enhanced resistance to chlorides and acids, used in chemical and marine applications.
• AISI 904L – superior resistance to sulfuric acid and warm seawater, selected for highly corrosive processes.

Manufacturing Process

The mesh is produced by precision weaving of stainless steel wire to achieve the desired aperture and wire diameter. For tighter tolerances or higher strength, the woven mesh can be sintered, which fuses the wire intersections while preserving the open area.

Applications

In pharmaceutical micron‑filtration, the mesh retains particles as small as 5 µm while allowing sterile liquids to pass, ensuring product purity without frequent cartridge replacement.

In chemical catalyst recovery, the mesh supports catalyst beds under high temperature and corrosive flow, providing mechanical support and enabling efficient separation of solids from liquids.

In food processing, the mesh is used for sieving powders and granules, where its smooth surface reduces product buildup and facilitates cleaning-in-place (CIP) procedures.

Quality Control

• Opening size verified by laser diffraction or optical microscopy with tolerance ±2 µm.
• Wire diameter measured via micrometer, ensuring conformity to ±0.005 mm.
• Visual inspection for defects such as broken wires, misweaves, or surface contamination.
• Burst pressure testing for sintered meshes to confirm structural integrity under expected operating conditions.

Customization Options

• Custom panel sizes up to 1500 mm × 3000 mm with edge treatments such as hemmed, welded, or flanged.
• Alternative weave patterns: plain Dutch, twill Dutch, or reverse Dutch to modify flow characteristics.
• Surface finishes: electropolished for reduced product adhesion or passivated for enhanced corrosion resistance.
• Integration with frames, gaskets, or housing components for direct installation.

Frequently Asked Questions

Can dimensions be customized?

Yes. Width, length, and shape can be tailored to suit specific equipment housings. Edge finishes and mounting features are also adjustable.

What information is required before quotation?

Required details include desired mesh opening (µm), wire diameter, stainless steel grade, panel dimensions, and any special edge or surface treatment.

How is quality inspected?

Inspection involves laser measurement of aperture, micrometer verification of wire diameter, visual defect checks, and, for sintered meshes, burst pressure testing.

What packaging methods are available?

Meshes are packed in moisture‑resistant sheets, placed in rigid cartons or wooden crates, and sealed with desiccant packs to prevent corrosion during transit.
