Abstract
An investigation was undertaken at Purdue University of the corrosion by steam of various stressed samples of steels which are available for high-temperature service. Apparatus was constructed and techniques developed for measuring the amount of corrosion on stressed specimens. Data are presented in this paper, showing the effect of stress upon the corrosion of Carbon-Moly, 1.25 Cr-Moly, 2 Cr-Moly, 7 Cr-Moly, 9 Cr-Moly, and 18-8 stainless-steel samples. Within the range of the test conditions stress does not influence the penetration or corrosion due to high-temperature steam. No intergranular attack took place except for a small amount in the case of Carbon-Moly steel during a 2000-hr test. Chromium content increases the resistance of steels to corrosion by high-temperature steam.
