| Temper | Wall | Yield MPa | Tensile MPa | Elong. % |
|---|---|---|---|---|
| F · 20 °C | Not specified | 190–220 | 350–380 | 7–10 |
F at 20 °C condition: 2018 supplier foldout F condition tested at 20 °C; the 2015 handbook prints the same numerical row but leaves temper and ageing time blank. Wall thickness and specimen protocol are not reported.
Brinell hardness, F condition: 80–100 HBW
Chemical composition
Only reviewed weight-percent bounds are listed. A blank bound means only the other threshold was reported.
The supplier 2015/2016 handbook and 2018 foldout disagree on five ingot-element limits and on the inequality direction of the 150 °C and 225 °C elongation cells. Those values are withheld, without averaging or calling the editions independent issuers. The 20 °C F row is the 2018 supplier condition, with matching numerical cells in the older handbook; the older table does not print an F temper. Its ageing time is blank. High-temperature strength cells are separately qualified observations, not complete mechanical conditions. Density and modulus are from the 2016 supplier physical table, whose measurement temperature is not reported.
