This report contains the res ults of measurements of corrosion madc on a variety of wrought and cast ferrou s mate rials after expos ure to different soil conditions for pcriods lip to 14 years.The steels ranged in composition from fractional percentages of nickel a nd chromium to the hi gh concentrations typical of wholl y austenitic steels.T ile soi ls ranged from well aerated soils deficient in soluble salts to poorly aerated soi ls containing high co ncentrations of water-soluble materials.The magnitude and p rogress of co rros ion w. ith respect to both weight loss and pitting are interpre"ted in relation to the properties of the soi ls at the test sites.A comparison is made of the co rr05ion of spccimens o f plain wrought materials and cast iron.'fA BL1~ 2.
