Good Agreement

The corrosion rates of low-carbon steel, and 304, 316 and 410/420 stainless steels in simulated geothermal media containing hydrogen sulfide have been measured by means of the polarization resistance technique. Good agreement was found between weight-loss and polarization resistance measurements of the corrosion rate for all the metals tested. Carbon steel formed a non-adherent film of mackinawite (Fe1 + xS). The lack of protection afforded to the steel by the film resulted in an approximately constant corrosion rate. The stainless steels also exhibited corrosion rates that were independent of time. However, the 410 and 420 alloys formed an adherent film consisting mainly of troilite ( FeS ) which provided only limited passivity. In contrast, the 304 and 316 alloys appeared to be essentially protected by a passive film which did not seem to involve an iron sulfide phase. However, all the stainless steels, particularly the 410 and 420 alloys, showed pitting, which indicated that some breakdown of the passive films occurred.

Compositional Properties

Abstract Oxide films on stainless steels have been classified into three types according to film thickness, film structure, film composition, and influence of the film on resistance to corrosion. Compositional properties of oxide films isolated from surfaces of stainless steels were studied using specially developed microanalytical techniques. Properties of passive films on stainless steel were evaluated and the effects of alloy composition and surface treatment on other types of films on Types 304, 316, and 347 stainless steels were studied. The influence of corrosion in various media was correlated with film compositional properties. Composition of films after immersion in acids was found to be related to film composition prior to immersion. The effect of immersion depended on the nature and intensity of corrosion and was reflected most sensitively by the iron and silicon contents of the films. The conclusion was made that film properties indicate strongly the capacity of austenitic stainless alloys to develop corrosion-resistant surfaces in certain environments.
