British Steel S96 Equivalent to a US Steel

British Steel S96 Equivalent to a US Steel

British Steel S96 Equivalent to a US Steel

(OP)
We need a equivalent for a 1980 British tool steel S96. What i found so far was:

Element Min % Max %
C 0.27 0.35
Si 0.15 0.35
Mn 0.45 0.70
P - 0.025
S - 0.015
Cr 0.50 0.80
Mo 0.45 0.65
Ni 2.3 2.8
Al 0.015 0.05

B-basis Ftu = 906 MPa (131 ksi) & t2 = 711 MPa (103 ksi) (t2 = 0.2% proof stress).
Izod is 54 J at 6" thick.

B.S. S154 spec. requirements are:
Ftu 880 to 1080 MPa (128 to 157 ksi), t2 690 MPa (100 ksi) min, e = 12% min, Izod 40 J min.

Hardness: 255 to 321 HB and 270 to 340 HV as hardened and tempered.
In the softened condition (reached by heating at 650 C (1200 F)) hardness must be <= 248 HB (Ftu =~ 120 ksi?).

Heat treat (durations unspecified).
Harden: 850+-10 C (1560+-20 F), cool in oil.
Temper: 600 C (1110 F), cool in air.

S96 crosses to S154
2½ % Nickel chromium-molybdenum steel billets, bars, forgings and parts (880-1080 MPa: limiting ruling section 150mm)

RE: British Steel S96 Equivalent to a US Steel

There isn't an exact North American equivalent. There are a number of standard Ni-Cr-Mo grades that are similar, including 4330, 4340, 35NCD16, and 300M.
