Simulation Study on the Austenisation and Cooling Behaviors of the Medium-Mn Steel
The austenisation and quenching behaviors of a medium-Mn steel with a chemical composition of C 0.14% and Mn 5.0% were presented in this paper.The heating and holding temperature varied from 500℃ to 950℃ was applied to find the austenization temperature.The holding time varied from 1-5minutes was used to choose the suitable austenisation time.Air cooling were applied to check the hardening capacity of the studied steel.It was found that the tensile strength is lower than 900Mpa and total elongation varied from 20-30% when the austenisation temperature is lower than 700℃.However, the tensile strength could be high up to 1600MPa and the total elongation about 12% when the austenisation temperature is higher than 700℃ with air cooling.Based on the low austenisation temperature and the air hardening capacity, it was proposed that the studied medium-Mn steel could be used as the hot stamping steel in the car industry.
