Interpretation of the ISO 2892:2007 Austenitic Cast Irons
摘要
Abstract
The basic properties of austenitic cast irons material in ISO 2892:2007 were introduced, such as good heat and corrosion resistance, good impact resistance at very low temperatures, oxidation resistance, low thermal expansion and the advantage of being non-magnetic. The stable austenitic matrix precludes the opportunity to enhance mechanical properties by heat treatments, because the applicable heat treatments are confined to providing stress relief and high temperature stabilization. Stress relief is applied to remove those stresses, whereas stabilization is used where castings are required to maintain close tolerances. The austenitic matrix structure provides a range of important properties that are dependent upon the metal composition and particularly upon the chromium, manganese, molybdenum and silicon contents. Section sensitivity occurs in the austenitic cast irons, which are different from the flake graphite and spheroidal graphite grades.关键词
