An addition of 0.006 wt-%Ca tothe stpel may improve the hardenability, reduce the critical cooling rate of transformation ofpearlite or bainite under continuous cooling and increase the M_s. AES analysis showed thatthe Ca segregates markedly along austenitic gfain boundaries, and accelecrates the segrega-tion of C, Cr and Si. It is believed that besides towards deoxidizing and desulphurizing as wellas imperoveing sulphide morphology, a trace of Ca in 58CrV steel behaves towardsmicroalloying.
