改善Super304H 不锈钢抗晶间腐蚀性能的途径
Approach to Improve Intergranular Corrosion Resistance Performance of Super304H Stainless Steel
摘要
Abstract
This paper firstly states characteristics of M23 C6 in Austenitic stainless steel in aspects of ingredients,structural features,relationship between Cr-depleted zone and impacts of interface,alloying elements and stress states on precipitati-on.Taking superheater pipe of the supercritical pressure boiler and Austenitic Super403H stainless steel often used for rehea-ter pipe as examples and combining ingredients and characteristics of Super304 H stainless steel,it proposes to improve sensi-tivity of intergranular corrosion of Super304H by means of adjusting grain boundary engineering,optimizing high tempera-ture softening technics,speeding up formation of M23 C6 and increasing sensitizing technics.At last,it points out that stud-ying on laws of sensitizing process of Super304H stainless steel is a future research direction .关键词
