Import 304 316 Etching Stainless Steel — Buy in wholesale FOB from Supplier in China

304 and 316 etching stainless steel from Hebei Anping County Shengda Hardware Wire Mesh Co.Ltd is austenitic chromium-nickel alloy sheet material processed by chemical etching to create precise surface patterns and textures. Grade 304 contains 18% chromium and 8% nickel (typical), while grade 316 adds 2-3% molybdenum for enhanced pitting resistance in chloride environments. The supplier offers both grades with customizable thickness and dimensions, shipped on metal pallets with standard export packing. Etching depth and pattern can be specified according to project requirements, with the process controlled through photoresist masking and ferric chloride or nitric acid exposure.

The base material conforms to ASTM A240 standard composition for chromium and nickel content, with grade 316 providing superior corrosion resistance in marine and chemical processing environments. The etching process does not compromise the inherent passivation layer, provided post-etching passivation treatment is applied, which is standard practice. Surface finishes after etching range from matte to semi-reflective depending on acid concentration, temperature, and dwell time. Typical sheet thickness ranges from 0.5mm to 3.0mm for architectural and decorative applications, though heavier gauges are available for industrial use. The supplier's location in Anping, Hebei province, places it within China's concentrated metalworking corridor with access to cold-rolled coil feedstock from regional mills.

Primary applications include architectural facades, elevator panels, signage, filtration components, and decorative consumer goods where aesthetic surface texture combines with corrosion resistance. Food processing equipment manufacturers specify 316 grade for dairy and brewing applications where chloride exposure occurs. Medical equipment fabricators use etched 316 for instrument trays and sterilisation chambers requiring both hygiene and visual identification. Buyers should confirm exact alloy composition certificates, etching depth tolerances, and whether the supplier provides salt spray test reports per ASTM B117 or equivalent Chinese GB standard. Surface roughness Ra values after etching should be specified for applications where friction or flow characteristics matter.

Hebei Anping County Shengda Hardware Wire Mesh Co.Ltd is located in the West Development Zone of Anping County, Hebei Province, with a registered address at Shijiazhuang 050091. Anping is recognised as China's primary concentration for wire mesh and metal filtration product manufacturing, providing this supplier with dense local supply chains for stainless steel wire, sheet, and processing equipment. The supplier holds a harbor trust tier on the platform, though its response rate is recorded at 0.00% with an average response time of zero hours, indicating no engagement data is available from the platform's messaging system. Buyers should treat direct communication as essential before placing orders, given the absence of response history.

The company's product focus centres on hardware wire mesh and related stainless steel processed materials, including etched sheet products derived from standard cold-rolled coil. No verified factory size, annual revenue, employee count, or specific client references are stated in the available profile data. The supplier does not list ISO, CE, or other third-party certifications in its platform data, contrary to claims sometimes inserted by marketplace content, so buyers should request mill test certificates and material composition reports directly. Shengda's proximity to Tianjin Port (approximately 180km) provides standard export logistics access for containerised shipment of palletised metal goods.
