Product Description
1. Corrosion-Resistant Connection for Harsh and Humid Environments
This is our stainless steel sleeve nut, designed for applications in humid, outdoor, and corrosive environments such as marine equipment, chemical processing systems, and food machinery.
Unlike carbon steel fasteners, stainless steel provides inherent corrosion resistance, significantly reducing the risk of rust formation over long-term use. This ensures stable and reliable fastening performance in demanding environments.
2. Multiple Stainless Steel Grades for Different Applications
We offer three stainless steel material options:
- 304 stainless steel – general-purpose grade with good corrosion resistance and balanced cost performance
- 316 stainless steel – enhanced corrosion resistance, suitable for marine, saltwater, and chemical environments
- 410 stainless steel – higher hardness, suitable for wear-resistant applications with lower corrosion requirements
Internal thread sizes range from M6 to M30. Sleeve depth ranges from 8 mm to 75 mm, and wall thickness ranges from 2 mm to 5 mm, all customizable according to application requirements.
3. Verified Corrosion Resistance and Surface Finishing Options
Corrosion resistance is tested to ≥72 hours in neutral salt spray testing, meeting standard industrial durability requirements for stainless steel components.
Hardness is controlled at HRB 75–95, ensuring a balance between machinability and structural strength.
We offer two surface treatment options:
- Passivation – enhances natural corrosion resistance by improving surface stability
- Electropolishing – improves surface smoothness and cleanliness, suitable for applications requiring hygiene and aesthetic finish
With extensive stainless steel manufacturing experience, we maintain stable production quality and efficient cost control, ensuring competitive pricing and consistent product reliability.
