English
Our 316 Stainless Steel Shafts are designed for high-performance applications that demand superior corrosion resistance, durability, and precision. Manufactured using CNC machining techniques, each 316 SS shaft meets exact specifications with tight tolerances and consistent quality, making it an ideal choice for harsh and corrosive environments.
Whether you need custom CNC machined 316 shafts for marine use, chemical equipment, or food-grade machinery, our precision 316 stainless steel shafts deliver the strength and reliability required for critical components in industrial operations.
Why Choose 316 Stainless Steel?
316 stainless steel is an austenitic, non-magnetic alloy known for its exceptional resistance to corrosion, especially in chloride and acidic environments. Key advantages include:
Superior corrosion resistance – Especially in marine, saltwater, and chemical environments
High strength and durability – Withstands heavy loads and mechanical stress
Heat and oxidation resistance – Ideal for high-temperature industrial processes
Food and medical grade safety – Compliant with hygienic applications
Non-magnetic properties – Suitable for sensitive electronic and marine uses
This makes 316 stainless steel shafting rods perfect for long-term use in aggressive environments where other metals would degrade.
CNC Machining Capabilities
We use advanced CNC turning and milling centers to manufacture 316 stainless steel shafts with extreme precision. Our production capabilities include:
Tolerance: Up to ±0.01mm
Surface Finish: Ra ≤ 0.8μm
Shaft Diameter Range: 3mm – 200mm
Length Range: Up to 2000mm or customized
Processes: Turning, milling, centerless grinding, thread cutting, keyway machining
Each machined 316 stainless steel rotating shaft is produced with rigorous quality control and verified using CMM and surface roughness testers to ensure superior finish and concentricity.
Surface Treatments & Finishing
To meet specific operational needs, we offer optional surface treatments for your custom 316 stainless steel shaft:
Polishing / Mirror Finish – For improved aesthetics and low-friction movement
Passivation – To enhance corrosion resistance in chemical environments
Centerless Grinding – For consistent diameter and smoother operation
Heat Treatment (optional) – To improve hardness for wear resistance
These finishing techniques ensure your 316 stainless shaft performs efficiently and resists corrosion, pitting, and galling in challenging applications.
