The material for the piping system in a new power plant must be specified to carry hot aerated seawater used to cool steam. Stresses both static and cyclic are present in the pipe due to welding, weight of the pipe, and vibrations from the pumps. Flow will vary from stagnant to very rapid. Austenitic stain$$ less steel and $70$Cu$-30$Zn brass are being considered for the pipe. What forms of corrosion might be possible for each material? Which alloy would be better?
