0.8C-8Cr-2Mo-0.5V Steel

Steel name: 0.8C-8Cr-2Mo-0.5V
Diagram No.: 8250
Type of diagram: TTT
Chemical composition in weight %: 0.8% C and 0.8% C, 8% Cr, 2% Mo, 0.5% V
Steel group: Carbon steels, tool steels
Note: TTT diagram for a 0.8% C carbon steel and for a high-alloy tool steel (0.8% C, 8% Cr, 2% Mo, 0.5% V). P represents the pearlite transformation, M martensite, and C the precipitation of proeutectoid carbide. Observe that the pearlite nose shifts from 1 to more than 1000 s due to the effect of alloying elements in solid solution. Also notice that the martensite temperature increases after the precipitation of proeutectoid carbides in the high-alloy steel, as an effect of the decrease of alloying elements in solid solution.
