The aim of the paper was to investigate internal oxidation process under steam oxidation conditions and steam oxidation behaviour of two solid-solution strengthened alloys; UNS N06230, UNS N06617, two gamma - prime (i§â€™) strengthened UNS N07263 and UNS N07208. The samples have been tested under 1 bar pressure in 100% water – steam – water system in temperature range 700 - 800 oC for 3000 hours. The study has showed that Ni based solid-solution strengthened alloys; UNS N06230, UNS N06617 d...

The growing interest in more efficient electricity generation is driving research into steam oxidation of high temperature resistant steels. The main driver behind this is a clear dependence between the efficiency of a power plant and steam conditions (temperatures and pressures). The efficiency of the power plant increases with higher steam temperatures and pressures before expansion through the steam turbine. However, increased in steam temperatures significantly influence the oxidation rate o...

The aim of the work was to investigate corrosion resistance of highly alloyed steels and Ni-based alloys in a steam atmosphere for 1000 h at 700 °C. In these steam oxidation experiments, two solid solution strengthened alloys; Haynes® 230®, 617 alloy, two gamma-prime (γ′) strengthened alloys; 263 and Haynes® 282® and three Cr+Ni- rich stainless steels: 309S, 310S and HR3C austenitic steels were exposed. The study showed that the materials exposed commonly developed thin oxide scales; in Ni-based...

Abstract Two solid-solution strengthened alloys, (HAYNES ® 230 ® , 617 alloy), two gamma – prime (γ’) strengthened alloys, (263 and HAYNES ® 282 ® ) and Cr rich steels (309S, 310S and HR3C) were tested under 1 bar pressure in 100% steam at 800 °C for 3000 h. The steels showed better resistance in terms of corrosion behaviour, where no internal corrosion occurred. The exposed samples were characterised using SEM, EDS and XRD. Artificial neural networking (ANN) was used to predict kinetic behaviou...

Inconel 740H is a nickel-based alloy for pressure components of ultra-supercritical boilers. Its chemical composition and strengthened matrix, as well as corrosion resistance, provide the highest creep resistance among the materials recommended for use in high-performance pressure components of power units. This paper investigates the changes in the microstructure and mechanical properties after ageing at 700 and 750 °C for 1000, 10,000, 20,000, and 30,000 h. Observation of the microstructure wa...

Ferritic T23 steel and austenitic TP347HFG steel have been studied with an emphasis on understanding the impact of specimen geometry on their steam oxidation behaviour. The selected materials were tested over a wide range of temperatures from 600 to 750°C. The tests were carried out in 100% steam conditions for 1000 hours. The tests indicated that the ‘curved-shaped’ specimens show slower mass gain, scale ticking and void nucleation rates than ‘bridge-shaped’ specimens (with flat and convex surf...

The aim of this study was to investigate phase formation under steam oxidation conditions and steam oxidation behaviours of two solid-solution-strengthened alloys—HAYNES® 230® and 617 alloy—two gamma-prime (γ′)-strengthened alloys—263 and HAYNES® 282®—and finally three austenitic steels rich in Cr—309S, 310S and HR3C. The samples were tested under 1 bar pressure in 100 % water–steam–water system at 800 °C for 1000 h. It was found that Ni-based solid-solution-strengthened alloys, HAYNES® 230® and...

The paper reports high temperature resistance of ferritic steels in fireside corrosion regime in terms of temperature and deposits aggressiveness. Four candidate power plant steels: 15Mo3, T22, T23 and T91 were exposed under simulated air-fired combustion environment for 1000 h. The tests were conducted at 600, 650 and 700 °C according to deposit-recoat test method. Post-exposed samples were examined via dimensional metrology (the main route to quantify metal loss), and mass change data were rec...

This publication studies the steam oxidation behavior of advanced steels (309S, 310S and HR3C) and Ni-based alloys (Haynes® 230®, alloy 263, alloy 617 and Haynes® 282®) exposed at 800 °C for 2000 h under 1 bar pressure, in a pure water steam system. The results revealed that all exposed materials showed relatively low weight gain, with no spallation of the oxide scale within the 2000 h of exposure. XRD analysis showed that Ni-based alloys developed an oxide scale consisting of four main phases: ...
