Corrosion tests were made in a recirculating test loop operating with 290 deg C, deionized, deoxygenated water at pH 10 to determine the effects of several heat treatments on the corrosion rate of ASTM A212 Grade B carbon steel. The heat treatments were a 700 deg F stress relief, an 1192 deg F anneal, a 1450 deg F anneal, and a 1650 deg F normalize. These heat-treated samples were compared with cold-worked material. For all heat treatments, including the coldworked samples, the corrosion rate was found to be 0.15 mils/yr. An analysis of the iron release rate to the water indicated that a high release rate occurs initially for fresh metal surfaces but the release rate is reduced to a linear rate of 0.41 mg/dm/sup 2//day after 500 hr exposure.
