    Jun 22, 2011 · The major influence on CVN impact energy is carbon content for steel. The lower the carbon content, the lower the ductile to brittle transition temperature along with higher upper shelf CVN impact energy values. Since you confirmed my suspicion as this being a HSLA steel and is probably fine grained and Q&T, the CVN numbers make sense.
