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

Duplex 1.4462 is the combination of the best properties of all types of stainless steel. The result is an excellent resistance against pit corrosion and it is even more rustproof than AISI 316 . Duplex steels are magnetic, a property that can be used to easily differentiate them from common austenitic grades of stainless.

The elastic limit (or: yield point), which is more than double that of AISI 316, a lower expansion coef cient and less tendency to torsion, make this the ideal basic material for a top-notch propeller shaft.

Craftsman Marine propeller shafts are carefully straightened and ne-machined, complete with taper 1:10, keyway and thread for the nut cap. Key, brass nut cap and zinc anode are included. Available from 1 to 3 metres in 0.5 metre increments.
