Values marked * are engineering estimates. Cost index is indicative and is not a quotation. Missing values are shown as —. For sourced reference grades, ranges and ">" values are stored at conservative lower bounds, and strengths reported in kgf/cm² are converted to MPa. Max service temperature is shown as supplied, without an assumed atmosphere.

Typical values are for engineering guidance only. Actual properties depend on grade, processing, and test conditions. Please confirm the final specification with Cortenna before production.
