Welcome to Dongguan HonHo Jewelry Co., Ltd. Since 2010, we have been a trusted manufacturer specializing in precision components. Our Industrial Stainless Steel Ring, made from 304 material and precision ground for mechanical seals, represents the culmination of over a decade of engineering excellence. With a factory spanning 3,000–5,000 square meters and a dedicated team of 51–100 skilled workers, we ensure every ring meets stringent quality standards. These rings are designed to provide reliable sealing performance in demanding industrial applications, offering exceptional durability and corrosion resistance.
Our precision ground stainless steel rings are crafted from high-grade 304 stainless steel, known for its excellent mechanical properties and resistance to oxidation. The precision grinding process ensures a smooth, flat surface that minimizes friction and wear, extending the life of your mechanical seal assembly. Each ring is manufactured to comply with international standards, providing consistent dimensions and performance batch after batch.
Key Features & Technical Specifications
- Material Quality: 304 stainless steel (0Cr18Ni9) – offers good corrosion resistance and formability.
- Precision Grinding: Achieves fine surface finish and tight tolerances (±0.01 mm typical).
- Standard Compliance: Manufactured to meet common mechanical seal standards (e.g., DIN, ANSI).
- Versatile Sizes: Available in a wide range of diameters and thicknesses; customizable per your drawings.
- Consistent Hardness: Typically HRC 20–30, ensuring wear resistance without brittleness.
- Low Surface Roughness: Ra values as low as 0.2 μm for reduced leakage.
| Parameter | Value / Range |
| Material Grade | 304 (UNS S30400) |
| Outer Diameter | 10 mm – 500 mm (custom) |
| Thickness | 1 mm – 20 mm (custom) |
| Surface Finish (Ra) | 0.2 μm – 0.8 μm |
| Tolerance | ±0.01 mm – ±0.05 mm (depending on size) |
| Hardness | HRC 20–30 (typical) |
| Corrosion Resistance | Suitable for water, oils, mild chemicals |
These rings are ideal for use in pumps, compressors, mixers, and rotary equipment where reliable sealing is critical. The precision ground surface reduces friction, leading to lower energy consumption and extended seal life. Furthermore, our standard-compliant manufacturing ensures that the rings can be directly integrated into existing mechanical seal designs without additional modification.
