Continuously hot-dip coated steel flat products - Technical delivery conditions EN 10346:2009

Publication date:   Jul 10, 2009

Scope

This European Standard specifies requirements for continuously hot-dip coated products made of low carbon steels for cold forming, of steels for construction, of steels with high proof strength for cold forming and coated with zinc (Z), zinc-iron alloy (ZF), zinc-aluminium alloy (ZA), aluminium-zinc alloy (AZ) or aluminium-silicon alloy (AS), and for continuously hot-dip coated products made of multiphase steels for cold forming coated with zinc (Z) zinc-iron alloy (ZF) or zinc-aluminium alloy (ZA) with thicknesses of 0,35 mm to 3 mm unless otherwise agreed.
The thickness is the final thickness of the delivered product after coating.
This document applies to strip of all widths and to sheets cut from it (above or equal to 600 mm width) and cut lengths (< 600 mm width).
NOTE 1 Products coated with (pure) aluminium can also be available, but are not covered by this European standard.
NOTE 2 By agreement at the time of enquiry and order, this European Standard is applicable to continuously hot-dip coated flat products in thicknesses < 0,35 mm or > 3 mm with agreed mechanical properties, adhesion of coating and surface condition requirements.
NOTE 3 The products covered by this European Standard are used where cold formability, high strength, a defined minimum yield strength and corrosion resistance are the most important factors. Corrosion resistance of the product is proportional to the coating thickness, hence to its mass (see also 7.3.2). The products covered by this European Standard can be used as substrates for organic coated flat products specified in EN 10169-1 and EN 10169-2 or EN 10169-3 for building and general engineering applications.
NOTE 4 By agreement at the time of enquiry and order, this European standard is applicable to other continuously hot-dip coated hot rolled steel flat products (e.g. in accordance with EN 10149-2).
