The corrosion behavior of irradiated and unirradiated stressed stainless steel containing minor natural B additions was studied in static 600 deg F water containing 10 g/l of boric acid. Alloys of AISI Type 304 stainless steel containing 0, 0.03, and 0.05 wt % B were investigated. Descaled metal losses after 1000 hr of exposure ranged from 6 to 30 mg/dm/sup 2/ for irradiated and unirradiated specimens of the alloys tested. These specimens were free of selective attack. The corrosion resistance of the alloys tested was essentially the same regardless of the irradiation dosage before corrosion (9.6 x 10/sup 19/ nvt thermal and 3.58 x 10/sup 18/ nvt fast). No differences were observed in amount of attack in 600 deg F borated water for exposure times of 100 and 1000 hr. The attack under the test conditions appears no more severe than that reported for unstressed unirradiated austenitic stainless steels exposed to neutral or slightly alkaline high-purity water.
