Stainless steel is susceptible to stress corrosion when exposed to chloride bearing water. Nuclear naval vessel piping may be damaged from bilge water splashing insulated piping, permeating the insulation and eventually contacting the pipe wall. A test apparatus was set up for this project to simulate this condition. The control tests conducted in this apparatus with 1 in. Type 304 stainless steel specimens have shown that chloride stress corrosion will result. Effort is being directed to combat the corrosion by surveying industrial practices and using this information to set up experimental procedures for testing promising preventive methods. The substitution of an alternative material for stainless steel has been suggested as a second course in the elimination of the potential hazard of chloride stress corrosion. Inconel has been put forth by the Bureau of Ships as an alternative material. Inconel pipe specimens have not corroded under the same conditions which resulted in corrosion with stainless steel specimens. further testing with Inconel is being performed with heat treated specimens.
