X11CrMoWVNb9-1-1 (grade E911) Steel

Steel name: X11CrMoWVNb9-1-1 (grade E911)
Diagram No.: 9496
Type of diagram: CCT
DIN designation: X11CrMoWVNb9-1-1 (grade E911)
Chemical composition in weight %: 0.115% C, 0.20% Si, 0.51% Mn, 0.017% P, 0.002% S, 8.35% Cr, 0.94% Mo, 0.24% Ni, 0.22% V, 0.95% W, 0.069% Nb, 0.007% Al, 0.064% N
Steel group: Creep resistant steels
Note: Austenitizing temperature: 1060 C, time: 30 min. It is recognizable a final fully martensitic microstructure is obtained in a wide range of cooling rates encompassing the entire arc welding characteristic values, with Ms temperature nearly insensitive, as well. In this situation the as-cooled (as-welded) microstructure may have hardness in excess of 400 VHN mainly controlled by the carbon content only.
