Heat-resistant steel at high temperature with high thermochemical stability and thermal strength of special steel, called heat-resistant steel.Heat-resistant steel improves oxidation Resistance The elements chromium, aluminum, and silicon are commonly used to form a lethal, stable, continuous, and strong oxide film on the surface of the steel.When aluminum and silicon obviously increase the brittleness of steel, they are often added together with chromium. When chromium > 5%, the operating temperature can reach 600 to 650℃.When the chromium is 28%, the working temperature can reach 1100℃.Secondly, the oxidation resistance of heat-resistant steel can be improved obviously by using trace rare earth elements such as yttrium and lanthanum to prevent preferential oxidation of grain boundary at high temperature.Three, metal surface chromizing, aluminum, silicon also effectively improve the oxidation resistance of steel.
