Description
Heat resisting nickel-free chromium ferritic steel, alloyed with yttrium, zirconium and lanthanum, is suggested for production of components of heat-exchange and heating equipment operating in oxidative gaseous media at temperatures up to 1300 deg C. The steel possesses sufficiently high mechanical properties, at test temperature 1300 deg C the grain size corresponds to 4-5 points. Corrosion depth for 1200 hrs at 1300 deg C constitutes 0.03-0.04 mm
