Description de produit
Product Description
This marine-grade stainless steel 316 CNC turned propeller shaft delivers superior corrosion resistance for saltwater environments. Featuring Ra 0.4μm surface finish and ±0.02mm taper accuracy, the shaft is manufactured from 316 stainless steel that withstands 500+ hours of salt spray testing without pitting. Passivated finish further enhances corrosion resistance. Each shaft is dynamically balanced and inspected with precision runout measurement.
As a leading CNC turning manufacturer with over 15 years of precision machining experience, we produce Marine Grade Stainless Steel 316...

Frequently Asked Questions
Q: Why 316 over 304 for marine applications?
A: 316 stainless steel contains 2-3% molybdenum which provides significantly better resistance to chloride pitting and crevice corrosion in saltwater compared to 304. We recommend 316 for any seawater-exposed application.
Q: What is the maximum shaft length you can produce?
A: We can CNC turn shafts up to 1500mm in length with consistent diameter tolerance. Longer shafts available with center-rest support.
Q: Do you provide dynamic balancing?
A: Yes, we perform dynamic balancing to G6.3 or better grade on all rotating shafts. Balance certificates are provided.
