3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
structural material
material used for the manufacture of a specific component of an aerospace system, structure or engine
3.2
alloying element
see EN 4500-00 1
3.3
unalloyed metal
metal that contains no alloying elements and with a total impurity content less than 0,5 %
For the applications of this standard, a so-called commercially pure” metal is not considered as unalloyed metal and its designation shall be chosen according to the same rules as those of the relevant metallic alloys
3.6
powder metallurgy material
material divided into solid particles at least in the first step of its solid state processing
3.7
steel
iron base material alloyed with carbon the content of which is generally lower than 2 %
3.8
unalloyed steel
see EN 10020
3.9
low alloy steel
steel alloyed with one or several metallic elements, the mean value of the content of each being less than 5 % and the content of at least one being higher than the carbon content
3.10
high alloy, ferritic or martensitic steel
steel alloyed with one or several metallic elements, the mean value of the content of at least one of which is equal to or higher than 5 % and the crystalline structure of which contains less than 40 % of austenite in Its condition of use
high alloy, austenitic or austenitic-ferntic steel
steel alloyed with one or several metallic elements, the mean value of the content of at least one of which is equal to or higher than 5 % and the crystalline structure of which contains 40 % austenite or more in its condition of use
3.12
joining material
material used for the metallurgical assembly of several parts of an aerospace system
3.13
filler metals for welding
joining material solidus temperature of which is dose to or the same as the solidus temperature of the materials to be joined
3.14
feller metals for brazing
joining material solidus temperature of which is significantly lower than the solidus temperature of the materials to be joined
— the method of melting,
— the heat treatment,
— the form,
NOTE The method ol melting may induce variations in the mass content of one or several alloying elements. These variations are not considered significant and shall not be taken into consideration
4.2 ASD-STAN designation
ASD-STAN designation is not applicable to new standard and revision for:
— nickel base or cobalt base alloys (see 5.2, EN 10027-1 and EN 10027-2),
— steels (see 5.4, EN 10027-1 and EN 10027-2),
— commercially pure titanium and titanium base alloys (see 5.5).
The ASD-STAN designation of each material comprises nine characters divided into three groups:
A group of three characters consisting of:
— the symbol of the base metal in accordance with ISO 80000-9, but written entirely in capital letters,
— dash(es) for completion to three characters.
A group of five characters:
— the first three characters indicate the alloying elements (one, two or three) considered significant (with the exception of all aluminium base materials). It the chemical composition is such that there is only one or two alloying elements, the remaining character(s) is (are) a zero.
The use of this group of three characters is defined in each of the relevant following clauses. In addition, one character indicates the method of production for structural materials or the use for joining materials (see 4.3).
— the last two of this group of five characters (or the last character in the case of cast aluminium base alloys, see 5.3.2) form a serial number starting at 01 (or 1 in the case of cast aluminium base alloys. see 5.3.2). This serial number shall be changed every time the first three and the last five characters already allocated do not fit the new basic chemical composition to be designated.
The conventional designation is unique for one basic chemical composition, except for certain filler metals for brazing (see 6.2.2.2 and 6.2.2.3).BS/EN 2032-001-2014 pdf download.
