WebDec 1, 2024 · The Si-free 9 wt% Cr F/M steel investigated in this study involves a relatively high oxidation rate, especially when the temperature reaches 600 °C. The formation of thick Fe-, Cr-rich spinel layer not only increases the risk of oxide scale exfoliation, but also reduce the heat transfer of base material [1], [40]. Alloying with Si (≤1.0 wt ... WebDec 1, 2024 · Nickel-chromium alloys with very high content of chromium over the subcritical value (≈15 wt%Cr) are well known for high affinity to oxygen and high stability of Cr 2 O 3 at high temperature [5].
