DP1400, DP1000, DP800 Steels
Steel name: DP1400, DP1000, DP800
Diagram No.: 7278
Type of diagram: CCT
Chemical composition in weight %:
DP1400 steel: 0.19% C, 0.55% Si, 1.61% Mn, 0.02% Cr, 0.05% Ni, 0.04% Al, 0.003% Ti, 0.00% B, 0.006% N
DP1000 steel: 0.15% C, 0.57% Si, 1.45% Mn, 0.01% Cr, 0.03% Ni, 0.04% Al, 0.003% Ti, 0.00% B, 0.003% N
DP800 steel: 0.12% C, 0.24% Si, 1.45% Mn, 0.02% Cr, 0.04% Ni, 0.03% Al, 0.002% Ti, 0.00% B, 0.004% N
Steel group: Alloy steels
Note: Calculated diagrams. For the prediction of the CCT diagrams, the austenization temperature was
chosen 927°C and the cooling rates of 0.01s-1 to 100s-1 were assumed. The
martensite starts temperatures (Ms) for DP1400, DP1000 and DP800 are
estimated approximately 420°C, 440°C and 450°C, respectively. The trend of
the temperatures is correct, because by increasing the carbon content, the
martensite start temperature is decreased.
