Import 304 Stainless Steel Cold Rolled Coil — Buy in wholesale FOB from Supplier in China

Mercure New Materials Co., Ltd. supplies 304 stainless steel cold rolled coils from Wuxi, Jiangsu Province, with grades certified as AISI 304, SUS 304, S30400, or 1.4301 under multiple international standards. The cold rolled thickness range spans 0.3mm to 3.0mm, with widths from 10mm to 2000mm and standard mill widths of 1000mm, 1220mm (4 foot), and 1500mm. Surface finishes include 2B, BA, No.4, HL, brushed, 8K mirror, embossed, and etched options, with paper or PVC film protection available. Edge options are slit edge and mill edge, with coil or cut-to-length supply formats.

The chemical composition conforms to standard 304 specifications: carbon maximum 0.07%, manganese 2%, sulfur 0.03%, phosphorus 0.045%, silicon 0.75%, chromium 17.5-19.5%, nickel 8-10.5%, and nitrogen 0.10%. Mechanical properties vary by temper: annealed condition achieves minimum 30 KSI yield strength, 75 KSI tensile strength, and 40% elongation with HRB 92 maximum hardness. Cold-worked tempers increase yield strength to 75-110 KSI and tensile to 125-150 KSI with corresponding elongation reduction to 12% or 6-7% depending on hardness level (25-37 HRC range).

Applications span chemical equipment and piping, heat exchanger components, dairy and food handling equipment, cryogenic vessels, and architectural structures in non-marine atmospheres. The material cannot be hardened by thermal treatment; annealing requires heating to 1850-2050°F with controlled cooling through 1500-800°F to prevent chromium carbide precipitation. Stress relief of cold worked parts is performed at 750°F for 0.5 to 2 hours. Brand options from major Chinese mills include TISCO, BAO STEEL, BAOXIN, ZPSS, LISCO, and JISCO, with third-party inspection by SGS available.

Mercure New Materials Co., Ltd. is located in Wuxi, Jiangsu Province, China, with postal code 214000. Wuxi is a major stainless steel distribution and processing hub in China, with extensive cold rolling, slitting, and surface finishing infrastructure serving domestic and export markets. The supplier carries a harbor trust tier. The response rate and average response hours both display as zero in the available data, so buyers should initiate direct contact to assess communication responsiveness. The profile does not indicate whether Mercure operates as a mill-direct supplier, a service centre with processing equipment, or a trading company sourcing from multiple mills.

The listing explicitly references major Chinese mill brands (TISCO, BAO STEEL, BAOXIN, ZPSS, LISCO, JISCO) as available sources, suggesting Mercure may operate with mill authorization or as an independent distributor with multi-source procurement capability. Third-party inspection through SGS is mentioned, alongside mill test certificates. What the profile does not disclose includes: years in operation, annual turnover, warehouse or stockholding capacity, in-house processing equipment (slitting lines, cut-to-length, polishing lines), or specific client references. The detailed technical specification suggests commodity expertise, though buyers should verify actual stock availability against the full product matrix rather than assuming all combinations are immediately deliverable.
