Abstract:
Within the framework of this work, alloys with a chromium content of 5 to14 wt%, aluminum from 0 to 4 wt% and silicon from 0 to 4 wt%. The samples were tested for resistance to oxidation with calm dry air (800 ∘C, 0.1 MPa) for 60 hours; in high parameter water (350 ∘C, 16 MPa), for 300 hours; in steam (400 ∘C, 10 MPa), for 72
hours and superheated steam (1100 ∘C, 0.1 MPa) for 1 hour.The compositions most resistant to corrosion under the specified conditions were determined, and the existence of a synergistic effect of silicon and aluminum as
alloying elements of iron alloys was confirmed.
