Since the introduction to modified 9Cr-1Mo steel (G steels including the Gr.91 have been developed an increasing the steam temperature to improve thermal chemistry and heat treatment conditions for these CS such as creep strength are strongly influenced by fabrication. These steels have already been included i experiences with these steels throughout the manufa Society of Mechanical Engineers (ASME), Boiler a issues and taken the actions to improve or revise the and discussion results.
