Name

Description and applications

F

Free machining status

Suitable for molding process, the hardening and heat treatment conditions without special requirements, the mechanical properties of the state of the product is not specified

O

Annealed condition

Apply fully annealed to obtain the lowest strength of processed products

H

Hardening state

Applies to improvement in strength by work hardening products, after hardening can pass (or not been) reduced the strength of the additional heat treatment H code must be followed by two or three digits

W

Solution heat treatment

An unstable state, only applies after solution heat treatment, the natural aging of the alloy at room temperature, the state code only that the product is natural aging stage

T

Heat treatment
(UnlikeF、O、H)

Products T Code applies to heat-treated later, after (or without) hardening reach steady state must be followed by one or more digits

TX finely divided state on behalf No. Description and application

State on behalf of the No.

Description and applications

T0

After solution heat treatment, the natural aging through the cold state, and apply to the cold working to increase the strength of the product

T1

By the high-temperature molding process cooling, then naturally aged to substantially stable state for the hot forming process cooling, no longer cold (can be straightening, flattening, but does not affect the mechanical properties of the limits) of the product

T2

Cooling the hot molding process, natural aging after cold working to a substantially stable state, suitable for forming a high temperature by the cooling process after cold working, straightening or flattening to increase the strength of the product

T3

Cold working after solution heat treatment, and then by natural aging to a substantially stable state, apply after solution heat treatment, cold working, or straightening. Leveler to increase the strength of the product

T4

Natural aging after solution heat treatment to a substantially stable condition applies to solution heat treatment after cold working longer (can be straightening, flattening, but does not affect the mechanical properties limit) Products

T5

By the high-temperature molding process cooling, and then artificially aged condition, suitable for cooling after the high-temperature molding process, without cold (can be straightening, flattening, but does not affect the mechanical properties of the limit), to be artificial aging products

T6

Post-state solution heat treatment applied to artificial aging after solution heat treatment, no longer cold (can be straightening, flattening, but does not affect the mechanical properties limit) Products

T7

After solution heat treatment overaged state suitable for solution heat treatment, to obtain some important characteristics, in the artificial aging, strength in the aging curve crossed the highest point of the product

T8

After solution heat treatment after cold working, and then artificially aged state
Apply to the cold, or straightening, flattening to increase the strength of the product

T9

Artificial aging after solution heat treatment and cold working of the state, apply to the cold working to increase the strength of the product

T10

After the high-temperature molding process cooling, cold, and then artificially aged state, apply to the cold, or straightening, flattening to increase the strength of the product

Note: some 6XXX alloy system, both the solution heat treatment furnace, or from high-temperature molding process to preserve the soluble ingredients quench in solid solution, solution heat treatment can achieve the same effect, T3 these alloys, T4, T6, T7, T8 and T9 status can be any one of the two heat treatment methods.


TXX and TXXX broken state code description and application

State on behalf of the No.

Description and applications

T42

Applicable since the O or F state solution heat treatment, natural aging to sufficiently stable state product, but also to the demand side of any state of processed products after heat treatment, the mechanical properties of the products reached the state T42

T62

Applicable since the O or F state solution heat treatment, artificial aging products, but also to the demand side of any state of processed products after heat treatment, the mechanical properties of the products reached the state T62

T73

After suitable solution heat treatment, after aging in order to achieve the required mechanical properties and resistance to stress corrosion index products

T74

And T73 is defined in the same state. T73 is greater than the tensile strength of the state of the state, but the state is less than T76

T76

And T73 is defined in the same state. Tensile strength of the state were higher than T73, T74 status, resistance to stress corrosion cracking were lower than the T73, T74 state, but it can still good exfoliation corrosion resistance

T72

Applicable since the O or F state solution heat treatment, artificial aging treatment, mechanical properties and corrosion resistance of the product reached T7X state

T81
