| Condition |
Description |
| O |
soft-annealed – this condition can be used for products where the properties required for the soft-annealed condition are achieved by soft annealing |
| H12 |
strain-hardened - 1/4 hard |
| H14 |
strain-hardened - 1/2 hard |
| H16 |
strain-hardened - 3/4 hard |
| H18 |
strain-hardened - 4/4-hard (fully hardened) |
| H19 |
strain-hardened extra-hard |
| H111 |
annealed and slightly strain-hardened by subsequent stages,
e.g. stretching or fl attening – (less than H11) |
| H22 |
strain-hardened and recovered - 1/4 hard |
| H24 |
strain-hardened and recovered - 1/2 hard |
| H28 |
strain-hardened and recovered - 4/4-hard (fully hardened) |
| H32 |
strain-hardened and stabilised - 1/4 hard |
| H34 |
strain-hardened and stabilised - 1/2 hard |
| T3 |
solution annealed and cold formed naturally aged |
| T39 |
solution annealed and cold formed by a certain degree to achieve the specifi ed mechanical properties; cold forming can take place before or after natural ageing |
| T4 |
solution annealing and naturally aged |
| T6 |
solution annealed and artificially aged |
| T7 |
solution annealed and overhardened (artificially aged) |
| T73 |
solution annealed and overhardened (artificially aged)
to achieve an optimum resistance to stress corrosion cracking |
| T8 |
solution annealed, cold formed and artificially aged |
| T9 |
solution annealed, cold formed naturally aged |
