25CrMo4 Chemical Element Composition Content (%)

Component	C	Si ^*	Mn	P	S	Cr	Mo
Minimum Value	0.22	0.1	0.6	-	-	0.9	0.15

◎ Steels with machinability which has been improved either by the addition of lead or by higher sulfur levels up to about 0.100 % (m/m) S (including controlled sulfide morphology) may be available on request.
* Steels may be supplied with a lower silicon content, in which case alternative means of deoxidation must be used.
