Abstract

A propeller has been considered as one of the most critical elements in propelling ships. However, only a little research on the marine propeller has been carried out. Furthermore, fractures of the propeller have been frequently caused by fatigue, but only tensile strength, yield strength and elongation are discussed in Register of Shipping. For the above reasons, we have evaluated strength properties of A1BC3 and HBsC1, both which have been used for the marine propeller by using air jet chisel and then, presented a method of improving the strength.
