What are TMCP (Thermo-mechanically Controlled Processed ...
Controlled rolled down from the normalising temperature, yet fully austenitic (above the Ar 3 temperature) followed by a rapid cool of approximately 10°C/sec. The aim of this process is to refine the grain size by controlled rolling and to increase the strength by suppressing the formation of ferrite and pearlite in favour of a strong tough bainite.
