27、ncontrolled Copy, (c) BSI Page 3 EN 10154 : 1996 BSI 1996 1) Until it is transformed into a European Standard, either EURONORM 12 or the corresponding national standard may be applied. 1 Scope This European Standard specifies requirements for continuously hot-dip aluminium-silicon alloy coated flat
28、products made of low carbon steels for cold forming (see table 1) or of structural steels (see table 2) in thicknesses # 3,0 mm. The thickness is the final thickness of the delivered product after coating. This European Standard applies to strip of all widths and to sheets cut from it ($ 600 mm widt
29、h) and cut lengths ( 600 mm width). The aluminium-silicon alloy coating is obtained by immersing the products in a bath containing 8 % to 11 % Si (also referred to as type 1). The available coating masses, coating finishes and surface qualities are given in 5.2 to 5.4 and table 3. The products cover
30、ed by this European Standard are mainly used where heat resistance and corrosion resistance are the most important factors. This European Standard is not applicable to steel flat products with hot-dip coating of pure aluminium (normally referred to as type 2 coating). 2 Normative references This Eur
31、opean Standard incorporates by dated or undated references, provisions from other publications. These normative references are cited at the appropriate points in the text and the publications are listed hereafter. Subsequent amendments to, or revisions of, any of these publications apply to this Eur
32、opean Standard only when incorporated in it by amendment or revision. In the case of undated references the most recent edition of the publications referred to applies.

35、1)Bend test for steel sheet and strip less than 3 mm thick 3 Definitions For the purposes of this European Standard the following definitions apply in addition to the definitions in EN 10020, EN 10021, EN 10079 and EN 10204: 3.1 hot-dip aluminium-silicon alloy coating (AS) Application of an aluminiu
36、m-silicon coating by immersing the prepared products in a molten bath of aluminium-silicon alloy. NOTE. In the present case, wide strip is continuously hot-dip coated in a bath the composition (type 1) of which is given in clause 1. 3.2 coating mass Total mass of coating on both surfaces of the prod
37、uct (expressed in grams per square metre). 4 Designation 4.1 The steel names are allocated in accordance with EN 10027-1 and CR 10260; the steel numbers are allocated in accordance with EN 10027-2. 4.2 The products covered by this European Standard shall be designated as follows in the order given:
38、a) type of product (e.g. strip, sheet or cut length); b) number of this standard (EN 10154); c) steel name or steel number and symbol for the type of hot-dip coating as given in table 1 or table 2; d) number denoting the nominal mass of coating (e.g. 080 = 080 g/m2including both surfaces, see table
39、3); e) letter denoting the surface quality (A, B or C, see 5.3); f) letter denoting the surface treatment (C, O, CO or U, see 5.4). EXAMPLE 1.

43、between 0,5 mm and 0,7 mm inclusive the minimum elongation values (A80) shall be reduced by 2 units. For product thicknesses less than 0,5 mm the values are to be agreed upon at the time of ordering. 4) This value applies to skin passed products only (surface qualities B and C). 5) See 5.1.2. EXAMPL

45、rmation to the designation as specified in 4.2 shall be given to describe clearly the delivery requirements (see clause 12). 5 Classification of grades and types of delivery 5.1 Steel grades 5.1.1 The steel grades available are given in table 1 and table 2. Table 1 contains low carbon steels listed
46、in the following order of increasing suitability for cold forming: DX51D+AS:bending and profiling quality; DX52D+AS:drawing quality; DX53D+AS:deep drawing quality; DX54D+AS:special deep drawing quality; DX55D+AS:special deep drawing quality, heat resistance up to 800 C. Table 2 contains structural s
47、teels listed in order of increasing specified minimum yield strength values. 5.1.2 Heat resistance may be assumed for temperatures up to 700 C except for steel grade DX55D+AS for which heat resistance may be assumed for temperatures up to 800 C. 5.2 Coatings 5.2.1 The coating masses are given in tab
48、le 3. For special applications coating masses which are different from those of table 3 can be supplied by agreement between the producer and the user. Thicker coatings limit the formability and weldability of the products. Therefore, the forming and weldability requirements should be taken into acc
49、ount when ordering the coating mass. 5.2.2 During hot dip coating, a Fe-Al-Si alloy layer forms over the base material and its thickness depends on the chemical composition and the metallurgical properties of the base material. If a maximum value for the mass of this layer is required, this shall be specially agreed upon at the time of ordering. The test method is described in annex B. 5.3 Surface quality 5.3.1 General The products may be supplied with one of the surface qualities described in 5.3.2 to 5.3.4 (see also 4.2e) and 6.8). 5
