Abstract: The network of soil corrosion of China, initiated in 1989 a soil burial program in representative corrosive soils utilizing 2 stainless steels(1Cr13 and 1Cr18Ni9Ti), The test soil sites contained acid, neutral, and alkaline soils. This report contains the results of 1Cr13 stainless steel obtained for specimens buried in the soils for up to 1,3,5 years.The results shown, there is slight corrosion of 1Cr13 stainless steel in acid or neutral soils and severe pitting corrosion in alkaline soils. The total contents of Cl and SO 4 2 in soils was the most important factor determining the corrosion behavior of 1Cr13 stainless steel in soils. The weight loss of 1Cr13 increases with the growing of the total contents of Cl and SO 4 2 in soils.

Key words: stainless steel, soil corrosion
