Charpy verses Hardness in 0.38 - 0.45% C steel
Charpy verses Hardness in 0.38 - 0.45% C steel
(OP)
I am trying to get a feel for what the low temperature (-15 Deg C / 5 Deg F) Charpy V notch energy for 1038-1045 steel when quench and tempered to 30-32 HRc.
I have conducted Charpy impact testing to normalized 1045 before and achieved only 6-7 J @ -15 Deg C. Will Quench and Tempering to 30-32 HRc get me up to 25-30 J @ -15 deg C?
Appreciate any insight you can offer.
