Focus On Marinox and Aquashaft

Marinox and Aquashaft identify a series of austenitic stainless steels precipitation hardening grades and duplex steels intended for the manufacture of propeller shafts in the shipbuilding industry.

Utilising these types of steel the designer can reduce the shaft dimensions and hence use smaller supports and seals.

The simultaneous reduction of weight and hydrodynamic resistance permits better performances and greater efficiency.
