Diese Europäische Norm enthält die Anforderungen an kontinuierlich schmelztauchveredelte Flacherzeugnisse mit Aluminium-Silicium-Überzügen aus weichen Stählen zum Kaltumformen (siehe Tabelle 1) sowie aus Baustählen (siehe Tabelle 2) in Dicken L 3,0 mm. Als Dicke gilt die Enddicke des gelieferten Erzeugnisses nach dem Schmelz-tauchen.
Diese Europäische Norm gilt für Band aller Breiten sowie für daraus abgelängte Bleche (3 600 mm Breite) und Stäbe (< 600 mm Breite).
Der aus einer Aluminium-Silicium-Legierung bestehende Überzug wird durch Eintauchen der Erzeugnisse in ein Schmelzbad mit einem Siliciumgehalt von 8 % bis 11 % aufgebracht (auch als Typ 1 bezeichnet).
Die lieferbaren Überzüge, Auflagegewichte und Oberflächenarten sind in 7.2 bis 7.3 und in Tabelle 3 angegeben.
Die Erzeugnisse nach dieser Europäischen Norm eignen sich für Verwendungszwecke, bei denen Hitzebeständig-keit und Korrosionsbeständigkeit der Erzeugnisse im Vordergrund stehen.
Diese Europäische Norm gilt nicht für schmelztauchveredelte Flacherzeugnisse mit Überzügen aus reinem Aluminium (üblicherweise als Typ 2 bezeichnet).

Bandes et tôles en acier revetues en continu par immersion a chaud d'une couche d'Aluminium-Silicium (AS) - Conditions techniques de livraison

L'épaisseur considérée est l'épaisseur finale du produit livré apres revetement.
La présente norme européenne s'applique aux bandes (bobines) de toutes largeurs ainsi qu'aux tôles (largeur
* 600 mm) et aux bandes refendues coupées a longueur (largeur < 600 mm) qui y sont découpées.
Le revetement d'alliage aluminium-silicium est obtenu par immersion des produits dans un bain contenant 8 % a 11 % de silicium (aussi dénommés de type 1).
Les masses de revetement, aspects de revetement et qualités de finition disponibles sont indiqués de 7.2 a 7.3 et dans le tableau 3.
Les produits couverts par la présente norme européenne sont essentiellement destinés aux applications pour lesquelles la tenue a chaud et la résistance a la corrosion sont des facteurs tres importants.

1 Scope
This European Standard specifies requirements for continuously hot-dip aluminium-silicon alloy coated flat 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 width) 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 coatings, coating masses and surface qualities are given in 7.2 to 7.3 and Table 3.
The products covered 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

EN 10154:2002 (E)75.2OptionsA number of options are specified in this European Standard and listed below. If the purchaser does not indicatehis wish to implement one of these options, the supplier shall supply in accordance with the basis specification ofthis European Standard (see 5.1).a) any low carbon steel products suitable for the manufacture of a specific part (see 7.1.2);b) any special requirements for a maximum Al-Fe-Si alloy layer mass occurring during hot-dip aluminium-siliconcoating (see 7.2.2);c) any requirement for special applications on bright appearance (type B surface, see NOTE to 7.3.3) andprotection by a strippable film on one surface (see NOTE to 7.4.2);d) any products supplied free from coil breaks (see 7.5);e) any products supplied free from stretcher strains when cold forming (see 7.6.2);f) any maximum or minimum value for the coating mass per product surface (see 7.7.2);g) notification of which surface has been inspected (see 7.9.1);h) any testing for compliance with the requirements of this standard (see 8.1.1 and 8.1.2);i) any supply of an inspection document and type of document (see 8.1.2);j) any requirement for packing (see 10).6 Manufacturing processThe processes used in steelmaking and manufacture of the products are left to the discretion of the manufacturer.7 Requirements7.1Mechanical properties7.1.1The products shall be supplied on the basis of the mechanical property requirements in Table 1 andTable 2.7.1.2If specially agreed at the time of enquiry and order, products made of steel grades DX52D+AS, DX53D+AS, DX54D+AS, DX55D+AS and DX56D+AS with suitability for manufacturing a specific part may besupplied. In this case the values in Table 1 do not apply. The reject tolerances arising when the material isprocessed shall not exceed a specific proportion to be agreed upon at the time of enquiry and order.7.1.3If ordered in accordance with 7.1.1 the mechanical property values in Table 1 for the low carbon steelsapply for the following periods commencing from the date on which the products are made available by the works:¾ 8 days for steel grades DX51D+AS and DX52D+AS;¾ 6 months for steel grades DX53D+AS, DX54D+AS, DX55D+AS and DX56D+AS.7.1.4For the structural steel flat products the mechanical properties in Table 2 apply. A reduction in theformability may occur with time. It is therefore in the interest of the purchaser to use the products as soon aspossible.SIST EN 10154:2003
