AISI 4320 Strength
AISI 4320 Strength
(OP)
I am attempting to get AISI 4320 material forged for the following properties: 148ksi tensile minimum, hardness between 31 and 36 HRC and -40C impacts of 20ft-lbs. The information that I have found seems to suggest that these property requirements are not possible. If they are not, any suggestions for a low carbon content alloy steel that could make these properties?

You might consider 4330 or 4330V if you need to harden that thick of a section to 31/36 HRC and need good low temperature toughness.
