Description

Craftsman Marine propeller shafts are made of Duplex 1.4462 stainless steel.

Craftsman Marine propeller shafts are carefully straightened and fine-machined, complete with taper 1:10, keyway and thread for the nut cap. Key, brass nut cap and zinc anode are included.

Duplex 1.4462 combines all the best properties of diverent variaties of stainless steel. The result is an excellent resistance against pit corrosion and it is even more rustproof than AISI 316. Duplex steels are also magnetic, a property that can be used to easily differentiate them from common austenitic grades of stainless steel.
The elastic limit (or: yield point), which is more than double of AISI 316, a lower expansion coefficient and less tendency to torsion, make this the ideal basic material for a top notch propeller shaft.
