A new method for the measurement of static corrosion rates in aqueous systems at elevated temperature and pressure is briefly described. Data obtained by application of the method to ferrous systems are presented. These data include: (1) the corrosion rate of low carbon steel in distilled water at 600 F, (2) the effect of raising the pH in such systems, (3) the effect of thermal shock and of temperature rise on the corrosion rate, and (4) the effect of heat treatment of the metal on the corrosion rate. Comparison is made between the corrosion rates of low carbon steel and stainless steel and some data are included on the effect of the wall thickness of low carbon steel specimens on the rate of hydrogen effusion resulting from corrosion at 600 F.
