... temperature reached 1150 deg C. This type of selective oxidation at which the easily oxidized chromium burns, while the nickel is not attacked, is caused by mildly oxidizing gases and is sometimes designated as green rot. Under these conditions, chromium-containing steels and alloys whose oxidation resistance...

... chromium content was susceptible to s-phase formation when annealed under 800 deg C. The material selected was therefore unsuitable for the stress to be anticipated. In view of the required oxidation resistance, a chromium-silicon or chromium-aluminum steel with 6 or 13% Cr would have been adequate...

.... This form of internal oxidation is, in the case of Ni-Cr alloys, known as green rot. Alloys containing iron should be more resistant. As a preventive measure it was recommended to reduce the operating temperature of the strip sufficiently to allow the use of Fe-Ni-Cr alloys. Electric heating elements...

.... It is a solid solution strengthened alloy of Ni, Cr, and Fe with small additions of Al and Ti. The Cr in alloy imparts resistance to oxidation and corrosion. The high percentage of Ni maintains an austenitic structure so that alloy is ductile and also contributes resistance to scaling, general corrosion...

... in the chemical and food industries, but suitable only for temperatures up to 760 °C (1400 °F). The carbon in the steel reacted with the chromium to form carbides, removing the chromium from solution and reducing the oxidation resistance of the metal.

The relatively poor fatigue crack resistance of the H13 hot-worked tool steel could thus be accounted for, at least in part, by its limited oxidation resistance [ 11 ].
