Galonian, G E; Tymchyn, H L

A series of static autoclave tests was made to establish the corrosion rate of Inconel in various waters at 600 deg F and to determine its resistance to intergranular corrosion and stress-corrosion cracking. Tests of Inconel 132 welds and a bimetal weld-cladding joint between Inconel and Type 308 stainless steel were also made. The test results show that the two heats of Inconel tested possess a rate of metal loss up to 9 mg/dm/sup 2/-mo. No stress corrosion cracking, intergranular corrosion, or selective attack of weld samples or cladding samples was found. Hydrogenbearing water was the least corrosive and produced virtually no attack. The addition of ammorium hydroxide resulted in a smaller amount of corrosion than that observed with neutral water. Some effects of heat-treatment were evident in tests with ammoniated hydrogen-free water. (auth)
