As the P content is controlled by the reactions in BOF, the double slag technique has generally been applied to obtain low P killed steels. However, this technique is accompanied by the increase in operating time and the decrease of the yield of the steel. In,The Ductile Iron News,Figure 4 presents the results of the investigation carried out by Druschitz et al(6) on 65-45-12 ferritic Ductile Iron tested at slow strain rate (1% per minute) at room temperature, in contact with various liquid environments. Under these test conditions, no embrittlement was detected.
