STRESS CORROSION OF INCONEL IN 550 F AERATED SEA WATER (17,000 PPM CHLORIDE)
The stress corrosion resistance to 550 deg F aerated sea water containing 17,000 ppm chloride was determined for Inconel, Hastelloy-C and -X, A. 0. Smith weld overlay, and type 347 stainless steel as control. The tests were made under two conditions: (1) static autoclave with continuous immersion for 77 days and (2) tilting autoclave with alternate immersion for 39 days. Annealed Inconel and Hastelloys C and X were found not to be susceptible to U-bend stress corrosion cracking in (1), whereas type 347 stainless steel suffered transgranular fracture within a few days. In (2), Inconel resisted failure but showed some shallow fine intergranular pits, and the Hastelloys and weld overlay fractured in 1 to 12 days. The results are correlated with the nickel content of the alloys. (D.L.C.)
