temper codedescription
T1Cooled from an elevated temperature shaping process and naturally aged to a substantially stable condition.
T2Cooled from an elevated temperature shaping process, cold worked and naturally aged to a substantially stable condition.
T3Solution heat treated, cold worked and naturally aged to a substantially stable condition.
T4Solution heat treated and naturally aged to a substantially stable condition.
T5Cooled from an elevated temperature shaping process then artificially aged.
T6Solution heat treated then artificially aged.
T7Solution heat treated and overaged/stablilized.
T8Solution heat treated, cold worked, then artificially aged.
T9Solution heat treated, artificially aged, then cold worked.
T10Cooled from an elevated temperature shaping process, cold worked, then artificially aged.
hardening codedescription
H1Strain hardened only.
H2Strain hardened and partially annealed.
H3Strain hardened and stabilized.
H4Strain hardened and lacquered or painted. This assumes that thermal affects from the coating process affect the strain hardening; seldom encounted.
