25、y limits are defined; the characteristics of the temper are significantly different from those of all other tempers which have the same sequence of basic treatments and for which designations already have been assigned for the same alloy and product; the following are also defined if characteristics
26、 other than mechanical properties are considered significant: a) test methods and limits for the characteristics; or b) the specific practices used to produce the temper. 2 Normative references Not applicable. 3 Terms and definitions For the purposes of this document, the following terms and definit

Property (mechanical or physical) limits apply to indivi
35、dual alloy-temper-product combinations. 4.2 The temper designation follows the alloy designation; these are separated by a hyphen. 4.3 Basic temper designations consists of letters. If subdivisions of the basic tempers are required, these are indicated by one or more digits following the letter of t
36、he basic temper. These digits relate to a specific sequence of basic treatments, but only those treatments or operations recognized as significantly influencing the products characteristics are indicated. Should some other variation of the same sequence of basic operations be applied to the same all
37、oy, resulting in different characteristics, then additional digits are added to the designation. 5 Basic temper designations 5.1 F as fabricated This designation applies to the products of shaping processes in which no special control over thermal conditions or strain hardening is applied. For this
38、temper, there are no mechanical property limits specified. 5.2 O - Annealed This designation applies to products which are annealed to obtain the lowest strength temper. The O may be followed by a digit other than zero1. 5.3 H Strain-hardened This designation applies to products subjected to the app
39、lication of cold work after annealing (or after hot forming), or to a combination of cold work and partial annealing or stabilizing, in order to secure the specified mechanical properties. The letter H is always followed by at least two digits, the first indicating the specific combination of basic
40、operations and the second indicating the degree of strain hardening. A third digit indicates the variation of a two digits temper and it is used when mechanical properties, or others characteristics, differ from those of the two digits H temper to which it is added. 1Products achieving the required
41、annealed properties after hot forming processes may be designated as O temper. BS EN 515:2017EN 515:2017 (E) 7 5.4 W Solution heat-treated This designation describes an unstable temper. It applies only to alloys which spontaneously age at room temperature after solution heat-treatment. This designat
42、ion is specific only when the period of natural ageing is indicated; for example W 1/2 h. 5.5 T - Thermally treated to produce stable tempers other than F, O or H (for heat-treatable alloys only) This designation applies to products which are thermally treated, with or without supplementary strain-h
43、ardening, to produce stable tempers. The T is always followed by one or more digits indicating the specific sequence of treatments. 6 Subdivision of O (annealed) temper designations 6.1 O1 High temperature annealed and slow cooled2This designation applies to wrought products which are thermally trea
44、ted at approximately the same time and temperature required for solution heat-treatment and slow cooled to room temperature, in order to generate the correct ultrasonic response and / or provide dimensional stability. It is applicable to products which are to be machined prior to solution heat treat
45、ment by the user. Mechanical property limits are not specified. 6.2 O2 Thermo-mechanically processed This designation applies to wrought products subjected to a special thermo-mechanical treatment. It is applicable to products which are to be super-plastically formed prior to solution heat treatment
46、 by the user. 6.3 O3 Homogenized This designation applies to continuously cast drawing stock or strip, which are subjected to a high temperature soaking treatment to eliminate or reduce segregations, thus improving subsequent formability and or response to solution heat-treatment. 7 Subdivision of H
47、 (strain-hardened) temper designations Subdivisions are made according to the basic operations described in 5.3 and the final degree of strain hardening, as follows: 7.1 First digit after H: The first digit following the letter H indicates the specific combination of basic operations as follows: H1x
48、 Strain hardened only These designations apply to products which are strain-hardened to obtain the desired strength without supplementary thermal treatment. 2Formerly designated as T41. BS EN 515:2017EN 515:2017 (E) 8 H2x Strain-hardened and partially annealed These designations apply to products wh
49、ich are strain-hardened more than the desired final amount and then reduced in strength to the desired final level by partial annealing. For alloys that age-soften at room temperature, the H2x tempers have the same minimum ultimate tensile strength as the corresponding H3x tempers. For other alloys, the H2x tempers have the same minimum ultimate tensile strength as the corresponding H1x tempers and slightly higher elongation. H3x Strain-hardened and stabilized These designations apply to products
