高铝奥氏体不锈钢是一种通过表面形成Al203获得优异抗氧化性的新钢种。综述了近年来国内外高铝奥氏体不锈钢的研究现状,主要包括合金成分设计、Al元素对奥氏体不锈钢性能(抗氧化性能、抗蠕变性能、拉伸性能)的影响,并对Mn代Ni高铝奥氏体不锈钢做了简单介绍,最后展望了高铝奥氏体不锈钢未来的发展趋势。
High-aluminum austenitic stainless steel is a new type of stainless steel which can acquire the excellent oxidation resistance by forming Al2 O3 scale in austenitic stainless steel. The current research status of high-alumi- num austenitic stainless steel at home and abroad is analyzed through composition design of alloys, effect of aluminum on oxidation resistance, creep resistance and tensile property of austenitic stainless steel. And the Mn generated Ni high aluminum austenitic stainless steel is introduced. At last the trend in development of high-aluminum austenitic stainless steel is prospected.
