The Corrosion of Alloy Steels by High-Temperature Steam

This paper presents additional test results obtained at the Engineering Experiment Station of Purdue University dealing with the relative resistance to corrosion by steam of unstressed specimens of various alloy steels at temperatures between 1000 F to 1800 F. All of the steels tested, except for the very high chromium-nickel alloys, show rapid corrosion beyond a limiting temperature which increases with chromium content. Data are presented relative to the chemical composition of the scale layers formed during tests at 1500 F and 1800 F.
