I am interested to learn if there is a reliable method to correlate CVN data. Often, specs will ask to have the material tested at different temperatures. So, is it possible to evaluate if 30 ft-lb at 20 degree Farenheit is comparable to 20 ft-lb at 70 degree farenheit.?? Or any combination for that matter.... Thanks

No.There is no correlation. You have to develop a charpy S curve from actual testing to determine where the material will fall. And things change rapidly in the ductile to brittle zone.
