“…17a are replotted on a magnified scale. Previous studies [25][26][27][28][29][30][31] have also shown that silicon facilitates the formation of a chromia scale. Huntz et al [25] oxidized a steel, which was similar in composition to P91, except that it contained 0.45 wt% Si, at 600 and 950°C in Ar which contained trace amounts of H 2 and H 2 O.…”

“…Stott et al [30] speculated that the formation of silica precipitates during the early stages of oxidation facilitates the development of a Cr 2 O 3 scale on an Fe-14Cr-10Si alloy oxidized at 1000°C; however, there was no direct experimental evidence to support this speculation. Lepingle et al [31] studied the oxidation of a group of steels containing approximately 11.5 wt% Cr and various amounts of Si, Mn, Mo, and W in pure H 2 O at 600, 625, and 650°C. The authors comment that there is a ''joint influence'' of alloying elements on steam oxidation.…”

Effect of Alloy Composition and Exposure Conditions on the Selective Oxidation Behavior of Ferritic Fe–Cr and Fe–Cr–X Alloys

Selective oxidation behavior of ferritic martensitic Fe-Cr base alloys, exposed in various atmospheres containing combinations of O 2 , CO 2 , and H 2 O, were studied at various temperatures relevant to oxy-fuel combustion. This paper begins with a discussion of the required Cr content to form a continuous external chromia scale on a simple binary Fe-Cr alloy exposed in oxygen or air based on experiments and calculations using the classic Wagner model. Then, the effects of the exposure environment and Cr content on the selective oxidation of Fe-Cr alloys are evaluated. Finally, the effects produced by alloying additions of Si, commonly present in various groups of commercially available ferritic steels, are described. The discussion compares the oxide scale formation on simple binary and ternary Fe-Cr base model alloys with that on several commercially available ferritic steels.

“…1 illustrates the weight change data of the steels during the steam oxidation test, which are used to discuss the oxidation kinetics, for each steel and temperature, the data can be fitted to the relationship Dm = kt a [19] where Dm is the specific weight loss [mg cm -2 ], t the oxidation time [hours], k and a, constants. At two oxidation temperatures, the behaviour in oxidation of the P-91 steel is worse than that of AISI 430.…”

Environments containing water vapour are common in many industrial processes, such as power generation systems. Hence, long-term oxidation (1000 h) of P-91 and AISI 430 was studied at 650 and 800°C, in 100% H 2 O atmosphere. The oxidation resistance of the AISI 430 is better than that of the P-91, due to the formation of protective phases on the surface. At 650°C, a scale composed of Fe 3 O 4 , Fe 2 O 3 and (Fe,Cr) 3 O 4 is formed on P-91, although at 800°C the scale is mainly composed of Fe 3 O 4 and (Fe,Cr) 3 O 4 . On the other hand, on AISI 430 the scale is composed mainly of (Fe,Cr) 2 O 3 at 650°C, and at 800°C a layer of Cr 2 O 3 is formed and remains owing to the higher diffusion rate of Cr at this temperature than at 650°C, the latter of which compensates the Cr depletion by the degradation of the chromia scale.

“…Many researches have reported that the morphology of the scale from the steam oxidation depends on the oxidation condition. In the steam condition, protective chromium oxide (Cr 2 O 3 ) that is expected to be formed on the surface of the tube is retarded by the growth of nonprotective oxide (Lepingle et al, 2008 ;Żurek et al, 2004). Ueda and Maruyama investigated a superheater tube (JIS STBA27) that had been exposed at 550-575 o C for about 70,000 hour in power plant.…”

The development of supercritical (SC) and ultra-supercritical (USC) power plants requires materials with better corrosion properties. Deep understanding on the oxidation mechanism in the boiler environment is one of the important factors to support this development. In this work, high temperature oxidation of Fe-Cr steels in steam condition is reviewed. Several mechanisms that explain the effect of water vapor in the oxidation behavior the steel were presented.
