<p>Nickel chromium stainless steel is of austenitic composition specially controlled to enable achieving resistance to elevated-temperature oxidation and corrosion at desirably economical levels of alloy content as low as 10% chromium and 10% nickel. Oxidation and corrosion resistant characteristics of the steel particularly include resistance to air-water atmospheres and gasoline exhaust atmospheres that are cyclically heated and cooled with heating to temperatures as high as 1800.degree.F. and cooling to room temperature. Steel has special utility for automotive exhaust train components and is generally useful for cyclically heated structural articles.</p> |
