Import 316l Sus Steel Round Cufflink — Buy in wholesale FOB from Supplier in China

These 316L stainless steel round cufflinks are precision accessories machined from SUS316L, a surgical-grade austenitic stainless steel containing 16-18% chromium, 10-14% nickel and 2-3% molybdenum by mass. The 16mm diameter suits standard French-cuff shirts, and the hinged back closure provides secure fastening without additional parts. Electroplated white steel finish gives a bright, neutral tone that resists tarnishing under normal wear conditions. The supplier specifies an MOQ of 50 pieces, with free sample availability for qualification.

SUS316L differs from 304-grade steel in its enhanced molybdenum content, which improves pitting resistance in chloride-rich environments including perspiration and coastal humidity. The low carbon content (0.03% max, typical for L-grades) minimises sensitisation during welding or thermal processing, preserving corrosion resistance at grain boundaries. Surface hardness after cold working reaches approximately 200 HV, sufficient to resist scratching from shirt buttons and desk surfaces. The round blank form allows for secondary engraving or logo application without edge distortion.

Primary buyers include fashion accessory wholesalers, corporate gift suppliers, and uniform outfitters serving hotel, airline and hospitality sectors. The unisex classification and children's sizing in the source data suggest application across family-oriented gift sets and promotional lines. DIY tool accessory use indicates potential for craft-kit inclusion or jewellery-making supply channels. Buyers should confirm plating thickness in micrometres, as this determines longevity of the bright finish under repeated handling.

Bosen Metal Electronic Co., Ltd operates from No.67 Village, 3rd Tower, Tangxiayong Town, Shenzhen, Guangdong Province, postal code 518105, in the Pearl River Delta manufacturing corridor. The supplier holds a harbour trust tier designation on the platform, with a response rate of 0.00% and average response hours recorded at zero, indicating no quotation history or inactive enquiry management at time of listing. The company profile does not disclose year of establishment, employee count, revenue figures, or specific factory certifications, so these should be requested directly during due diligence.

The listing positions the company as a metalwork specialist with capability in 316L stainless steel jewellery production, including electroplating and hinged-mechanism assembly. The product range extends to tie clips and cufflinks with occasion-specific marketing for anniversary, engagement and wedding segments. Buyers should verify whether the supplier performs plating in-house or contracts this process, as this affects quality consistency and turnaround times. The address format suggests a multi-tenant industrial building rather than a dedicated facility; site visits or third-party verification would clarify manufacturing depth and capacity.
