0.2C-1.60/2.82/3.92Mn-1.6Si Steel

Steel name: 0.2C-1.60/2.82/3.92Mn-1.6Si
Diagram No.: 7985
Type of diagram: TTT
Chemical composition in weight %: See the table.
Steel group: High strength steels
Note: Diagram No. 1: Time-temperature-transformation (TTT) diagram of bainite for steel C during two-step Q&P treatment (isothermal dwell at 400 C). Note that BM is the maximum value of the bainite volume fraction. M50 and M75 indicate the temperature of 50 and 75 pct athermal martensite, respectively.
Diagram No. 2: Bainitic TTT diagrams for steel C subjected to the one-step Q&P treatment. Note that BM is the maximum value of the bainite volume fraction within 1800 s. M50 and M75 indicate the temperature of 50 and 75 pct athermal martensite, respectively.
