0.70C-1.01Si-1.0Mn-0.013Ti-34 ppm N-11 ppm B Steel
Steel name: 0.70C-1.01Si-1.0Mn-0.013Ti-34 ppm N-11 ppm B
Diagram No.: 8199
Type of diagram: TTT
Chemical composition in weight %:
Steel A: 0.70% C, 1.01% Si, 1.01% Mn, 0.003% P, 0.001% S, 0.013% Ti, 34 ppm N
Steel B: 0.70% C, 1.01% Si, 1.00% Mn, 0.003% P, 0.001% S, 0.013% Ti, 34 ppm N, 11 ppm B
Steel group: High carbon steels
Note: Figure shows the TTT diagram of steels A and B. The
nose temperature of pearlite transformation can be seen to
be about 625°C. The upper bainite area fraction in a temperature
range of 600°C or less and below the nose was
calculated and compared with the upper bainite area fraction
obtained when steel A was isothermally transformed at
500°C.
