SEAWATER CORROSION STUDIES OF SNAP-21 MATERIALS

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 r/hr (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).
