高氮钢，尤其是高氮不锈钢，由于其优异的性能和诱人的应用前景受到国内外钢铁材料界的广泛关注。在理论计算分析氮在钢中溶解行为的基础上，指出了高氮钢制备的主要技术难点；概述了目前高氮钢的主要制备方法，重点讨论了常压和高压电渣重熔高氮钢的特点和存在的问题；分析了用电弧渣重熔(ASR)法生产高氮钢的技术优势，认为用ASR法生产高氮钢是目前比较可行的方案。
A great attention has been paid to the high nitrogen steels (HNS), especially high nitrogen stainless steels in the world, because of their excellent properties and wide prospective applications in the future. The main difficult technical problems of manufacturing high nitrogen steels have been pointed out, based on the theoretical calculation and discussion of the behaviors of nitrogen solution in steels. The features and problems of manufacturing high nitrogen steels by the electroslag remelting method at normal atmospheric pressure and high pressure have been discussed in detail. The arc slag remelting (ASR) process will be a prospective method of manufacturing high nitrogen steels, which has some obvious technical advantages compared with other methods.
