16MnCr5 Steel
Steel name: 16MnCr5
Diagram No.: 5023
Type of diagram: CCT
Mat. No (Wr.Nr) designation: 1.7131
DIN designation: 16MnCr5
Chemical composition in weight %: 0.175% C, 0.159% Si, 1.133% Mn, 0.014% P, 0.022% S, 1.02% Cr, 0.017% Mo, 0.10% Ni, 0.02% Al
Steel group: Alloy special structural steels
Note: Cylindrical dilatometer samples (diamter =5 mm, L=10 mm) were heated up to an austenitizing
temperature of 1200 °C at a heating rate of 200 K/min, where the samples were
austenitized for 10 minutes and then cooled down to room temperature with different
cooling rates. The phase transformation kinetics from the evaluation of the elongation curves, assisted by
metallographic results, is presented in the CCT-diagram shown in Figure. The Ac1 and
Ac3 temperatures of the steel 16MnCr5 were determined to be 740 °C and 835 °C
respectively, while the martensite start temperature Ms was determined to be 400 °C.
Additionally, the Vickers hardness test HV10 was performed for every cooling rate.
