Abstract:

The corrosion rates of several SNAP-21 materials measured in seawater at ambient room temperature and pressure Hastelloy C, Hastelloy X, Titanium- 621, Berylco-165 have been compared to those measured in 200C seawater vapor Hastelloy C, Hastelloy X, in seawater under a hydrostatic pressure of 7000 psi Hastelloy C, Titanium-621, Berylco-165 23C and in seawater in an ionizing radiation field of 200,000 rhr Hastelloy C, Hastelloy X 30C. Significant increases in corrosion rate were observed only for Hastelloy C and Hastelloy X in hot seawater vapor approximately two orders of magnitude and for Hastelloy C in seawater under high hydrostatic pressure approximately an order of magnitude.
