Import 316 316l Stainless Steel Sintered Fiber Felt — Buy in wholesale FOB from Supplier in China

Sintered fiber felt in 316 and 316L stainless steel from Anping County Longyi Mesh Manufacture Co., Ltd is a non-woven metallic filtration medium produced by compressing and sintering randomly oriented stainless steel fibres at elevated temperature. The resulting structure delivers high porosity with uniform pore distribution, combining the permeability of depth media with the structural integrity and thermal tolerance of solid metal. Available standard sheet sizes include 500 by 1000 millimetres, 600 by 1200 millimetres, 1000 by 1000 millimetres, and 1200 by 1200 millimetres, with custom dimensions achievable against specification. Filtration precision spans 3 to 100 microns, and multi-layer constructions of one, two, or three plies can be engineered for graded density or protective prefiltration.

The fibre matrix construction typically comprises a protective layer, control layer, dispersion layer, and reinforcing layer, though the exact stacking sequence and fibre diameter distribution are subject to custom specification. 316L fibre felt extends corrosion resistance in chloride-bearing environments compared to 304-grade alternatives, with FeCrAl, 310S, Monel, Hastelloy, Inconel, nickel, and titanium fibres available for extreme temperature or chemical duty. Standard thickness varies with application, with typical rolled product ranging from 0.5 to 3.0 millimetres; the supplier confirms custom thicknesses to buyer requirement. Sintered fibre felt exhibits noise reduction capability, thermal conductivity for heat exchanger duty, and long service intervals under pulsing or back-flush regeneration cycles.

Primary import applications include chemical processing reactor vents, petrochemical catalyst recovery, polymer extrusion melt filtration, and high-temperature gas particulate capture where bag or ceramic media fail. Heat exchanger manufacturers integrate fibre felt for thermal management and simultaneous particulate protection in compact designs. Buyers typically source this material in roll or sheet form for fabrication into discs, cylinders, or pleated cartridges by downstream OEMs. The supplier's Hebei location offers proximity to raw stainless steel fibre sources and established sintering furnace infrastructure, though buyers must confirm the supplier's in-house sintering capability versus subcontracted processing.

Anping County Longyi Mesh Manufacture Co., Ltd operates from No. 88, Heping West Street, Anping Town, Hengshui City, Hebei Province, China, postal code 053600. Anping County functions as China's dominant wire mesh and metallic filtration manufacturing cluster, with concentrated supplier networks spanning raw material supply, weaving, sintering, and finishing operations. The company holds a Harbor trust tier, indicating verified business registration without implying third-party quality certification or financial auditing. Response metrics show zero recorded response rate and zero average response hours, which may reflect limited platform engagement rather than operational scale.

The supplier's disclosed profile omits founding date, employee count, factory footprint, annual turnover, and named customers. No ISO 9001, ISO 14001, or industry-specific certifications are listed. Their product focus encompasses sintered fibre felt, woven mesh, and sintered mesh laminates for industrial filtration and related applications. The custom specification narrative positions 316L fibre felt for chemical, petrochemical, and high-temperature gas applications with custom thickness and roll width capability, though buyers must independently verify actual production constraints, quality control procedures, and minimum order thresholds for custom specifications.
