ASME STP-PT-076

This report identifies and addresses discrepancies between ASME data, as reflected in the stress tables in ASME Section II Part D, and data from other codes and standards (EN, AS, etc.). Additionally, the report proposes action for resolving these discrepancies (either provide technical arguments to ex-plain the valid basis for the differences, or make recommendations for revising the stress tables).

Several sets of mechanical data for materials which were introduced from other codes and standards into ASME Section II/D Tables and Code Cases are being investigated in this report to detect and, whenever possible, explain differences. Originally, deviations of not more than 2% were considered to be acceptable. Since in other non-ASME codes and standards temperature dependence of the UTS is not considered, only yield stress and time dependent properties are being compared.
