Each ring undergoes strict quality control to ensure dimensional accuracy and surface consistency. Our in-house testing includes hardness measurement (Rockwell or Vickers) and corrosion resistance checks (salt spray test). For annealed rings, we guarantee ductility for bending or forming; for hard temper rings, we ensure springiness and durability under repeated stress. The combination of material purity and precision manufacturing makes our rings a reliable choice for OEM projects.

Frequently Asked Questions
Q1: What are the differences between 304 and 316L stainless steel rings?
A: 304 is a general-purpose grade with good corrosion resistance, suitable for most indoor applications. 316L contains molybdenum, offering superior resistance to chlorides, acids, and saltwater — ideal for marine, chemical, or food processing environments. 316L is also more hypoallergenic for jewelry.
Q2: Can I get rings with a specific hardness or temper?
A: Yes. We offer annealed (soft) temper for easy forming or machining, and hard temper (spring-like) for applications requiring high strength and wear resistance. Custom hardness ranges are available upon request.
Q3: What is the minimum order quantity (MOQ)?
A: Our MOQ is flexible depending on size and temper. For standard diameters, MOQ can be as low as 1,000 pieces. For custom specifications, please contact our sales team for a quote.
Q4: What surface finishes are available?
A: Standard finishes include bright (mirror), matte, and polished. We can also apply brushed, sandblasted, or other decorative finishes according to your requirement.
Q5: Do you provide free samples?
A: Yes, we offer samples for quality evaluation. Typically, sample cost is charged and refundable upon bulk order. The sample lead time is 3–5 working days.
Q6: How long does it take to ship a wholesale order?
A: For standard sizes and finishes, production takes 7–15 days. Shipping time depends on destination: 10–20 days by sea, 3–7 days by air. We ship from major ports in China (Shenzhen, Dongguan, Guangzhou).
Q7: Are these rings suitable for use in food or medical applications?
A: 316L stainless steel is food-safe and biocompatible, often used in medical instruments and food processing equipment. However, for specific regulatory compliance (e.g., FDA, EU), please confirm with our team to ensure the grade and finish meet your standards.
Q8: Can I customize the ring dimensions (OD, ID, thickness)?
A: Absolutely. We can produce rings with custom outer diameter, inner diameter, and thickness within our capability range (up to 200mm). Tolerance can be tightened to ±0.05mm for precision applications. Just provide a drawing or sample.
