THIS discussion of steels and protective treatments for use up to 1000 F is divided into three parts.
First, the factors involved in the selection of appropriate steels are covered, emphasis being placed on the role of martensitic chromium steels, which combine strength with rust resistance. The effects of rusting of these steels and its prevention, as well as elevated-temperature considerations, are discussed.
Second, stress-corrosion of martensitic chromium steels is covered, and ranges are established in which these steels are prone to failure by this mechanism.
Third, the authors deal with protective coatings and set down the temperature ranges in which the protective coatings are used to advantage.
