Abstract

Austenitic stainless steel 304 and 316L were exposed to actual atmospheric environments of South China Sea for half one year, and the in??,uences of microstructures on atmospheric corrosion behavior of the two stainless steels were investigated. The results showed that the average corrosion rate of the two stainless steels were about 10-3~10-4 mm/a, while the depth of pitting hole was up to ~10μm, the number and area of pitting corrosion for the 316L are less and smaller than that of 304, the result of potentiodynamic polarization shows that the pitting potential of 316L is higher than that of 304, which indicates that atmospheric corrosion resistance of 316L is excelled to 304.
