Dissimilar metal weld is essential in enabling the use of austenitic steels to join with ferritic steels in boiler as well as heat recovery steam generator (HRSG) operating at high steam temperature. Improvement of durability of dissimilar metal welds will significantly reduced maintenance costs and enhanced capability of plant cyclic operation. This paper focuses on development of rotary friction weld of T91 to 304H to improve joint durability due to reduction in local strain. In addition, friction weld of ferritic steel to nanostructured ferritic alloy (NFA) will be shown. Microstructure of the weld and property evaluation of the weld line will also be discussed.
