Description |
Application |
| -0 |
Annealed |
Applies to wrought products which are annealed to obtain the lowest strength temper, and
to cast products which are annealed to improve ductility and dimensional stability. The
0 may be followed by a digit other than zero. |
| -F |
As fabricated |
Applies to products of shaping processes in which no special control over thermal conditions
or strain hardening is employed. For wrought products, there are no mechanical
property limits. |
| -w |
Solution heat
-w treated |
An unstable temper applicable only to alloys which spontaneously age at room temperature
after solution heat treatment. This designation is specific only when the period of
natural aging is indicated; for example: W 1/2 hr. |
| -T 1 |
|
Cooled from an elevated-temperature shaping process and naturally aged to a substantially
stable condition. Applies to products which are not cold worked after cooling from an elevated-
temperature shaping process, or in which the effect of cold work in flattening or
straightening may not be recognized in mechanical property limits. |
| -T2 |
|
Cooled from an elevated-temperature shaping process, cold worked, and naturally aged to
a substantially stable condition. Applies to products which are cold worked to improve
strength after cooling from an elevated-temperature shaping process, or in which the effect
of cold work in flattening or straightening is recognized in mechanical property limits. |
| -T3 |
|
Solution heat treated, cold worked, and naturally aged to a substantially stable condition.
Applies to products which are cold worked to improve strength after solution heat treatment,
or in which the effect of cold work in flattening or straightening is recognized in
mechanical DroDertv limits. |
| -T4 |
|
Solution heat treated and naturally aged to a substantially stable condition. Applies to
products which are not cold worked after solution heat treatment, or in which the effect of
cold work in flattening or straightening may not be recognized in mechanical property
limits. |
| -T5 |
|
Cooled from an elevated-temperature shaping process and then artificially aged. Applies
to products which are not cold worked after cooling from an elevated-temperature shaping
process, or in which the effect of cold work in flattening or straightening may not be
recognized in mechanical property limits. |
| -T6 |
|
Solution heat treated and stabilized. Applies to products which are not cold worked after
solution heat treatment, or in which the effect of cold work in flattening or straightening
may not be recognized in mechanical property limits. |
| -T7 |
|
Solution heat treated and stabilized. Applies to products which are stabilized after solution
heat treatment to carry them beyond the point of maximum strength to provide control of
some special characteristic. |
| -T8 |
|
Solution heat treated, cold worked, and then artificially aged. Applies to products which
are cold worked to improve strength, or in which the effect of cold work in flattening or
straightening is recognized in mechanical property limits. |
| -T9 |
|
Solution heat treated, artificially aged, and then cold worked. Applies to products which
are cold worked to improve strength. |
| -T10 |
|
Cooled from an elevated-temperature shaping process, cold worked, and then artificially
aged. Applies to products which are cold worked to improve strength, or in which the
effect of cold work in flattening or straightening is recognized in mechanical property
limits. |
