    The fracture toughness properties of three steels (A516-70, A533B Class 1, and HY-130) are determined in two steel-quality levels (conventional and calcium treated). In addition, a conventional quality A543B Class 1 steel is similarly examined at two locations (quarterline and centerline). Both investigations involved comparing steels with differing inclusion structures. The primary effort was to establish the upper-shelf toughness differences found using the Charpy V-notch impact and dynamic tear tests compared with those found using J-integral determinations of JIc and KIc. The JIc determinations appeared to be more sensitive to changes in inclusion structure than either the Charpy V-notch or dynamic tear tests. This was established by comparing the toughness between quality levels and by measuring the anisotropy of toughness within a steel. Comparisons are made with the Charpy V-notch impact-KIc upper-shelf correlation values. Comments concerning the suggested graphical method for JIc determination are also given.
