Stress-corrosion of stainless steels

It is impossible in this chapter to do justice to the extensive amount of research that has been performed on the stress corrosion of stainless steels, and probably more papers have been written concerning the austenitic grades than on all of the other grades together. Numerous reviews have been published in recent years some of which are listed in references 66-71, but other equally useful reviews are available. 

Corrosion—While corrosion is usually not a concern on hot surfaces, recognize that all systems have shut down periods, with the probability that moisture will find ingress and condense. Many insulalions arc alkaline and have little adverse effect on iron and copper, but aluminum is affected adversely. A major concern is stress-corrosion of stainless steel induced by even trace amounts of soluble chlorides un ASTM Test Method maybe used.
