310S Stainless Steel Wire Mesh

310S stainless steel mesh (UNS S31008) is a  premium high-temperature & oxidation-resistant austenitic stainless steel weaved mesh. The "S" stands for "Low Carbon (≤0.08%)," which minimizes carbide precipitation during welding and high-temperature exposure.  Its primary characteristic is excellent resistance to oxidation and corrosion at elevated temperatures, combined with good strength and creep resistance.

 Mesh Types & Technical Specifications

(1)Woven Filter Mesh (Most Common)

Weave patterns: Plain Weave, Twill Weave, Dutch Weave (Plain Dutch/Twill Dutch)

Wire diameter: 0.05 mm ~ 3.0 mm;

Mesh count: 2 mesh ~ 250 mesh

Standard roll sizes: 1x30m, 1.22x30m, 1.5mx30m or Custom rolls/cut-to-size available

Surface: Annealed (standard), pickled & passivated (for critical corrosion service), bright finish

(1) Sintered & Special Forms

l Sintered Laminate Mesh: 3–5 layers (protective+filter+support); filtration rating 5 μm ~ 100 μm; thickness 1.2–4.5 mm; no mesh shifting, high mechanical rigidity

l Filter Discs/Cartridges/Pleated Elements: For pressure filtration, gas separation, high-temperature dust collection

l Crimped Mesh: For heavy-duty high-temperature screening

Main Performance & Advantages

Mechanical Properties (Annealed, Room Temperature):

· Tensile strength ≥520 MPa;     Yield strength (0.2% offset) ≥205 MPa;    Elongation (δ5) ≥40%;

· Non-magnetic (annealed; slightly magnetic after cold working);

· Not hardenable by heat treatment (annealing at 1140–1175°C, water quenching recommended)

Exceptional High-Temperature Performance

· Continuous Service: Withstands temperatures up to 1150°C (2100°F).

· Intermittent Service: Handles thermal cycling up to 1035°C (1900°F).

· It resists scaling (oxidation) in air and combustion atmospheres due to its high chromium and silicon content.

Good Corrosion Resistance

· Offers superior resistance to general corrosion compared to 304 and 316 in many environments.

· Resists corrosion in high-sulfur atmospheres (common in petrochemical furnaces) and molten salts.

High Creep Strength

· It maintains structural integrity under mechanical stress at high temperatures, preventing the mesh from sagging or deforming over time.

Common Applications

· Heat Treatment & Furnace Industry: Furnace liners, radiant tubes, heating element supports, high-temperature flue gas filtration

· Chemical & Petrochemical: High-temperature catalyst recovery, molten salt filtration, sulfuric acid plant high-temperature sections, incinerator exhaust filters

· Power Generation: Flue gas desulfurization (FGD), boiler air preheater screens, high-temperature dust removal

· Metallurgy: Molten metal filtration, slag separation, annealing furnace atmosphere purification

· Aerospace & Industrial Heating: High-temperature gas turbines, thermal processing equipment components
