The authors investigated the effect of most alloying elements which are traditionaly regarded as dangerous in low-alloy structural steels--sulfur, phosphorus, copper, arsenic, antimony, tin--on the proneness to temper embrittlement of steel 25Kh1M1F which is used for making large all-forged rotors of fixed and transport medium-pressure steam turbines. On the basis of the obtained results it may be concluded that from among the investigated alloying elements only phosphorus and antimony have a statistically significant effect on the proneness of fine-grained steel 25Kh1M1F to temper embrittlement, and the embrittling effect of phosphorus is much stronger than the embrittling effect of antimony.
