BS 970 709 M40

Chemical Composition

The carbon content of 709M40 is 0.36-0.44 %. P and S content are 0.035% max and 0.040 % respectively. The Excess content of P and S can cause the 709M40 alloy steel to break at low tensile strength forces. The Cr Content is from 0.90-1.20 % which ish high and so it's hardness is high. It also has additional Mo content of 0.25-0.35%.

C%: 0.36-0.44
Si%: 0.10-0.35
Mn%: 0.70-1.00
S%: 0.040 max
P%: 0.035 max
Cr%: 0.90-1.20
Mo%: 0.25-0.35
