Product Characteristics & Technical Specifications
Our 316L Stainless Steel Ring is meticulously engineered to deliver consistent performance and long-lasting beauty. Below are the key characteristics and benefits:
- Premium Material: Made from 316L stainless steel – a marine-grade alloy with superior resistance to rust, tarnish, and chemicals. Ideal for daily wear in harsh environments.
- Precise Inner Diameter: Exactly 18mm (US size 8 approximately), ensuring a comfortable fit. Tolerance kept within ±0.1mm for consistent sizing across bulk orders.
- Matte Surface Finish: A smooth, non-reflective texture that reduces fingerprints and scratches, giving a sophisticated modern look. The matte finish is achieved through controlled sandblasting and polishing processes.
- Corrosion Resistance: 316L stainless steel contains molybdenum, providing excellent protection against chlorides, acids, and saltwater. This ring can withstand repeated exposure to sweat, water, and cleaning agents without degradation.
- Customizable Options: Available in various sizes (from 5mm to 25mm+), finishes (polished, brushed, matte, patterned), and colors (PVD coating, electroplating). Engraving or logo imprinting is supported via laser etching or stamping.
- Wholesale & OEM Service: Minimum order quantity (MOQ) negotiable – as low as 100 pieces for standard designs. Bulk production capacity of up to 50,000 rings per month ensures timely delivery for large projects.
