Warm Stamping Technology of the Medium-Mn Steel
The microstructure and mechanical of 22MnB5 steel,Al-Si coated 22MnB5 steel,and medium-Mn steel are studied before and after hot/warm stamping process.The results show that the austenite temperature is 800℃ for medium-Mn steel to obtain the tensile strength of 1500MPa,which is much lower than that of 22MnB5 steel (950℃),medium-Mn steel obtain finer microstructure and no surface decarburization without protective atmosphere,the total elongation reaches 10%,which is higher than that of 22MnB5 steel (7.5% ).
