The cylindrical pressure vessel of metallic materials was subjected to internal fluctuating pressure in saltwater, and fatigue strength of the materials was determined experimentally as the effect of saltwater. The cylinders used in this experiment are mild steel (S45C), stainless steel (SUS310S), aluminum (A5056), copper (C1100) and brass (C3604) metal. The cylinder was filled with 3% saltwater similar to seawater. Saltwater is used as a medium in addition to water, turbine oil and castor oil. Fatigue behavior of the cylinder in the saltwater is obtained and depends on the materials. Fatigue strength of copper and brass metal is the highest of all materials, but aluminum metal is the lowest of all. We explain the effect of saltwater on the fatigue strength of all materials. We relate corrosion behavior of metals to the free energy change (ΔG) by the Gibbs. Corrosion and free energy change of copper and brass metal are less than other materials.
