27、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 1

35、nts than alloying elements, the method of melting, the heat treatment, the form. NOTE The method of 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 designati
36、on 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 co
37、mprises 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 indi
38、cate the alloying elements (one, two or three) considered significant (with the exception of all aluminium base materials). If 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 de
39、fined 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.
40、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 designati
41、on 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 2032-001:2014EN 2032-001:2014 (E) 8 4.3 Method of production or use A capital letter from the following series: Structural material - C for cast material, P for cast + wroug
42、ht material, R for powder metallurgy material. Joining material W for welding material, B for brazing material. 4.4 Basic chemical composition (base metal excluded) A group of five digits: 4.4.1 In the case of unalloyed materials, the first three digits indicate information as in 5.1. 4.4.2 In the c
43、ase of metallic alloys, with the exception of all aluminium base materials (see 5.3), the first three digits indicate the alloying elements (one, two or three) considered significant (see 5.1, 5.2, Annex B, Annex C, Annex D and 5.6 to 6.2). If the chemical composition is such that there is only one
44、or two alloying elements, the remaining digit(s) is (are) a zero. The use of this group of three digits is defined in each of the relevant following clauses. 4.4.3 The last two of this group of five digits form a serial number starting at 01. This serial number shall be changed every time the first
45、three and the last five digits already allocated do not fit the new basic chemical composition to be designated. NOTE In consequence of 4.1, 4.2 and 4.3, except for certain brazing materials (see 6.2.2.1 and 6.2.2.2) the first three and the last five digits correspond to one and only one basic chemi
46、cal composition, whatever the letter used as the fourth digit. 4.5 Mass content of an alloying element It shall be taken as the arithmetical mean of the limits of its range. If two alloying elements have the same mass content, they shall be written according to the alphabetical order of their intern
47、ational symbol. 5 Structural materials 5.1 Unalloyed metals With the exception of all aluminium base materials (see 5.3), the group of five digits of the designation comprises from left to right: a single capital letter U symbolic of this category, a number indicating the percentage of base metal af
48、ter the decimal point, completed with zero if necessary, last two digits as serial numbers (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).
