0.032C-7.23Ni-2.02Mn Steel
Steel name: 0.032C-7.23Ni-2.02Mn
Diagram No.: 4920
Type of diagram: CCT
Chemical composition in weight %: 0.032% C, 0.25% Si, 2.02% Mn, 0.011% P, 0.008% S, 0.47% Cr, 0.63% Mo, 7.23% Ni, 0.03% Cu, 380 ppm O, 250 ppm N
Steel group: High strength welding steels
Note: Austenitizing temperature: No data. CCT diagram constructed from results of dilatometry experiments. Also plotted is
the average result of two or three hardness measurements on each specimen. A CCT diagram compiled from dilatometry measurements is presented in bellow figure.. The Ac1
and Ac3 temperatures were measured to be 690 and 740 °C, respectively. Curves A and B represent
the fastest cooling rates and it was not possible to decipher the transformation temperatures
for these with any confidence due to the limitations of the equipment. For Curve C and
D transformation began between 370 and 375 °C while for Curves E and F the transformation
temperatures increased slightly to the region of 400 °C. The average hardness of two or three
measurements on individual specimens is presented under the related cooling curves.
