STUDY ON FAILURE MODE OF WELDED JOINTS FOR AUSTENITE STEEL WITH DISSIMILAR METALS ON HIGH-TEMPERATURE BOILER TUBES IN POWER PLANTS
as well as creep rupture strength limit and persistent strength limit of welded joints for austenite steel (such as 304H and 347H stainless steel) with dissimilar metals (such 2.25Cr-1Mo ferrite heatresisting steel etc.) after long-term service have been tested and studied. The said heat-resisting steel has comparatively extensive utilization in our country. The causes leading to aging and failure of the said joints have been comprehensively analysed from several aspects
namely structure aging
peformance variation
features of joint’s configuration
carbon migration
and thermal expansion coefficient of materials etc.
