Comparison
Method, assumptions and limitations
Side-by-side display of the composition limits and minimum room-temperature properties stored in the LOSTWAX materials database (first listed condition per grade). Highlighted rows differ between the selected grades. Similar composition does not make two grades equivalent; heat treatment, test requirements and the scope of each standard differ.
Interpreting differences
Highlighted rows show elements whose specified limits differ between the selected grades. A different limit is not necessarily significant, and identical limits do not make two grades interchangeable: required heat treatment, test conditions and the scope of the standards also count. The principles are explained under international equivalents.
