DESIGNATION OF THE BASIC STATES OF THE PROCESS

F: As fabricated

Applied to the semi-product fabrication process in which there are no special controls associated with the heat treatments or cold working processes carried out. No values have been established for the mechanical properties.

O: Annealed

Applied to semi-products with the purpose of achieving the state with the lowest strength.

H: Work hardened (Generally drawn/rolled).

Applied to semi-products with a strength that has increased after being cold worked, with or without an intermediate heat treatment to achieve a reduction in their mechanical properties.

W: Solution heat treated and cold worked

This state is only applied to alloys that spontaneously age at the ambient temperature after being heat treated and cold worked. This state is only used when the natural ageing time is indicated. For example, W 1/2 hour.

T: Heat treated to achieve structural hardening

Applied to semi-products that are heat treated to increase their mechanical strength, with or without additional work hardening, with the purpose of achieving a stable state.

 

SUBDIVISIONS OF THE BASIC ALUMINIUM TREATMENT STATES

1. SUBDIVISION OF STATE H: WORK HARDENED

1.1. The first digit after the letter H indicates the specific variation of the basic operations of the process according to the following:

H1: Work hardened only

The mechanical properties are achieved with final cold working.

H2: Work hardened and partially annealed

The mechanical properties are achieved with a final heat treatment. In general, this state has a larger elongation than H1 with the same strength.

H3: Work hardened and stabilised

Applied to semi-products hardened with cold plastic working, with mechanical properties that have been subsequently stabilised by a low-temperature heat treatment. In general, stabilisation reduces mechanical strength and increases ductility. This subdivision is only applicable to alloys that are softened at the ambient temperature if not stabilised, such as AlMg alloys.

1.2 The digit after H1, H2 and H3 refers to the mechanical properties of the semi-product:

HX2: 1/4 hard. Its tensile strength is approximately halfway between the annealed and semi-hard state.

HX4: Semi-hard. Its tensile strength is approximately halfway between the annealed and hard state.

HX6: 3/4 hard. Its tensile strength is approximately halfway between the semi-hard and hard state.

HX8: Hard. Maximum degree of work hardening generally used.

HX9: Extra hard. Its tensile strength exceeds that of the hard state. Odd digits indicate states in which the tensile strength is the mean corresponding to the states of adjacent even digits.

1.3 Third digit (x) in the subdivision of state H

The next three digits after the letter H are used to designate forgeable alloys:

H (x)11: : Applied to semi-products that maintain their cold working hardness after final annealing, which prevents them from being classified as annealed (0), but which can be classified as H(x)1. Example: The degree of hardness achieved by controlled stress straightening is described as H111 (elongation of approximately 1%).

H 112: Applied to semi-products that can be work hardened at high temperatures, for which a series of mechanical property limits have been established.

H 113: : Applied to sheets that maintain their cold working hardness after final annealing, which prevents them from being classified as annealed (0), but which can be classified as H(x) (elongation of approximately 3%).

 

2. SUBDIVISION OF T STATES: HEAT TREATMENT

Digits 1 to 10 after the letter T indicate the specific sequences of basic treatments, as described next.

T1: Cooled from an elevated temperature-shaping process and naturally aged

Applied to semi-products that are cooled down from the extrusion temperature at the adequate speed (cold working), with the purpose of increasing their mechanical properties with a subsequent natural ageing process. This state includes the products that are subject to flattening or straightening with stress after cooling down, with no significant effects on the product's mechanical properties.

T3: Solution heat treated (1), cold worked (1), work hardened and naturally aged

Applied to semi-products that are cold worked and then work hardened after a solution heat treatment or cold working, with the purpose of improving their mechanical strength. This state includes the products that are subject to flattening or straightening with stress after cold working, which have an impact on the product's mechanical properties.

T4: Solution heat treated (1), cold worked (1) and naturally aged

Applied to semi-products that improve their mechanical properties after being solution heat treated, cold worked and naturally aged. This state includes the products that are subject to flattening or straightening with stress, with no effect on the product's mechanical properties.

T5: Cooled from an elevated temperature-shaping process and artificially aged

Applied to semi-products that are cooled down with forced air at the adequate speed (cold working) from the extrusion temperature, with the purpose of increasing their mechanical properties with a subsequent artificial ageing process. This state includes the products that are subject to flattening or straightening with stress after cooling down, with no significant effects on the product's mechanical properties.

T6: Solution heat treated (1), cold worked (1) and artificially aged

Applied to semi-products that improve their mechanical properties after a sudden solution heat treatment and artificial ageing. This state includes the products that are subject to flattening or straightening with stress, with no effect on the product's mechanical properties.

T7: Solution heat treated (1), cold worked (1) and artificially overaged / stabilised

Applied to semi-products that are artificially aged after being solution heat treated and cold worked, exceeding the limit corresponding to the maximum strength, with the purpose of controlling some of the product's significant properties.

T8: Solution heat treated (1), cold worked (1), work hardened and artificially aged

Applied to semi-products that are work hardened to a certain level between being cold worked and artificially aged to improve their strength. This state includes the products that are subject to flattening or straightening with stress after cold working, which have an impact on the product's mechanical properties.

T9: Solution heat treated (1), cold worked (1), artificially aged and work hardened

Applied to semi-products that are cold worked after being solution heat treated, cord worked and artificial aged, with the purpose of improving their mechanical strength.

T10: Cooled from an elevated temperature-shaping process, work hardened and artificially aged

Applied to semi-products that are subject to a specific work hardening process after cooling down (cold working) and before they are artificially aged.

2.1 Second digit in the subdivision of state T

A second digit is added (it must not be 0) to indicate variations in the treatment that significantly alter the properties of semi-products. The most significant variations are:

T31: 1% Solution heat treated, cold worked and work hardened.

T31: 1% Solution heat treated, cold worked and work hardened.

T41: Solution heat treated and cold worked, cooled down at a specific temperature.

T35: 1.5 to 3% Solution heat treated, cold worked and controlled stress applied.

T36: 7% Solution heat treated, cold worked and work hardened.

T42: Solution heat treated from 0 or F, cold worked and natural ageing.

T62: Solution treated from 0 or F, cold worked and natural ageing.

T51, T52, T53, T54: Cooling down (cold worked) from the extrusion temperature with different cooling levels, achieving different final mechanical properties with the same type of artificial ageing.

T53: Cooling (cold worked), from the extrusion and double artificial ageing temperature.

T61: Solution heat treated, cold worked and artificially aged under conditions other than T6.

T72: Stabilisation treated after T42.

T73: Solution heat treated, cold worked and aged with double treatment (stabilised to improve the resistance to corrosion under stress and ageing conditions).

T74: Solution heat treated, cold worked in water at a temperature above 50ºC and ageing with double treatment (Stabilisation + Ageing).

T76: Solution heat treated, cold worked and aged with double treatment (stabilised to improve the resistance to exfoliation corrosion + Ageing).

T81: Solution heat treated, cold worked, work hardened with forming and artificially aged. 1.5 to 3% Stress hardened.

T83: Similar to T8 for the Simagaltok 63/EN AW 6063 alloy.

T86: Solution heat treated, cold worked, work hardened and artificially aged. The degree of work hardening is usually the result of 6% stress straightening.

T87: Solution heat treated, cold worked, work hardened with forming and artificially aged. The degree of work hardening is usually the result of 7% stress straightening.

T89: Solution heat treated, cold worked and work hardened to achieve the mechanical properties and artificial ageing.

T93, T94: Solution heat treated, cold worked and work hardened to achieve the mechanical properties.

2.2 Third digit (x) in the subdivision of state T

The third digit indicates the elimination of stresses by means of straightening with controlled stress, where:

T(x)51: Applied to semi-products, indicating the work hardening effects after final straightening with controlled stress (1 to 3%) after solution heat treatment and cold working. These bars will not be subject to subsequent straightening processes.

T(x)50: As in the previous state, but applied to extruded and drawn bars, sections and pipes: Work hardening percentage, straightened with controlled stress (3%), except for pipes (0.5 to 3%).

T(x)511: As in the previous state, but allowing a lower degree of drawing after controlled stress.
