Abstract
Oxidation resistance of thermo-mechanical processed
stainless steel 316L was studied. The samples were
oxidized in supercritical water with 150 ppb
inlet-dissolved O2 at 600 °C and 25 MPa. Results show
that the proposed thermo-mechanical processing improved
the oxidation resistance by altering the microstructure
of stainless steel 316L. It was observed that grain
boundaries volume fraction and crystallographic
orientation of austenite grains play an important role in
oxidation resistance of the material. In addition, oxide
exfoliation was completely prevented by applying 50% or
more rolling reduction during the thermo-mechanical
processing.
