Thermochemical stability refers to the ability of steel to resist the chemical corrosion of various media at high temperature, among which the most basic and the most important is the oxidation resistance. The thermochemical stability is mainly determined by the chemical composition of the steel. Adding human Cr, Al and Si to the antioxidant capacity, because Cr, Al and Si can form a compact and protective Cr with oxygen when oxidized at high temperature2O3,A12O3ating SiO2film.
