Austenitic cast steels of Cr25-Ni32-Nb grade have found wide application in chemical and petrochemical industries. This study discusses the problem of the kinetics of oxidation of these materials in the atmosphere of laboratory air at temperatures of 930 and 1000 oC. Considering the operating conditions of castings (centrifugally cast reformer tubes), the results of the oxidation test of specimens taken from the zone of columnar crystals and equiaxial grains were presented.
