Continuously hot-dip coated and electrolytically coated strip and sheet of multiphase steels for cold forming - Technical delivery conditions
1.1 This European Standard specifies requirements for continuously hot-dip coated and electrolytically coated flat products made of multiphase steels for cold forming (see Table 1, Table 3 and Table 4) coated with zinc (Z and ZE), zinc-iron alloy (ZF) or zinc-nickel alloy (ZN) with thicknesses of 0,35 mm to 3,0 mm, unless otherwise agreed (see 1.2).
The thickness is the final thickness of the delivered product after coating.
This European Standard applies to strip of a width ≥ 600 mm and sheets cut from it.
1.2 If agreed at the time of enquiry and order, this European Standard may also be applied to continuously hot-dip coated flat products of thicknesses > 3,0 mm. In this case the mechanical property, adhesion of the coating and surface condition requirements should also be agreed at the time of enquiry and order.
1.3 The products covered by this European Standard are mainly used where cold formability, high strength and corrosion resistance are the most important factors. Corrosion resistance of the coating is proportional to the coating mass (see also 7.3.5)
1.4 This European Standard is not applicable to:
continuously hot dip coated steel flat products made of low carbon steels (see EN 10327);
continuously hot-dip coated structural steel flat products (see EN 10326);

continuously organic coated (coil coated) steel flat products (see EN 10169-1, EN 10169-2 and
EN 10169-3);
electrolytically zinc-nickel coated cold rolled steel flat products (see EN 10271); and

3 Terms and definitions For the purposes of this document, the terms and definitions given in EN 10020:2000, EN 10021:2006,
EN 10079:2007, EN 10204:2004 and the following apply. NOTE General definitions and guidelines for the protection of iron and steel can be found in EN ISO 14713. 3.1 hot-dip zinc coating (Z) application of a zinc coating by immersing the prepared products in a molten bath containing a zinc content of at least 99 % (see also 7.3.2.2) 3.2 hot-dip zinc-iron coating (ZF) application of a zinc coating by immersing the prepared products in a molten bath containing a zinc content of at least 99 %; subsequent annealing produces an iron-zinc coating with an iron content of normally 8 % to 12 % (see also 7.3.2.3) 3.3 electrolytic zinc coating (ZE)
application of a zinc coating by electrolysis on a suitably prepared steel surface from an aqueous salt solution by the use of an electric current 3.4 electrolytic zinc-nickel coating (ZN) application of a zinc nickel coating by electrolysis on a suitably prepared steel surface from an aqueous salt solution by the use of an electric current NOTE Flat products may have a zinc or zinc-nickel coating on one or both surfaces. If both surfaces are coated, a different coating thickness may be applied on each side (this process is referred to as differential zinc or zinc-nickel coating). 3.5 FB (ferritic-bainitic) steel steel containing, independent of the rolling process, bainite or strengthened bainite in a matrix consisting of ferrite and/or strengthened ferrite
NOTE The strengthening of the matrix is caused by a high density of dislocations, by grain refinement and precipitation of micro-alloying elements 3.6 DP (dual-phase) steel steel with a ferritic matrix containing a martensitic second phase present in the form of islands and eventually bainite as a complementary phase
NOTE According to their high tensile strength levels, dual phase steels show a low yield strength ratio and a high work hardening rate 3.7 TRIP (transformation induced plasticity) steel steel with a mainly ferritic matrix containing retained austenite which can transform to martensite (TRIP effect) during the forming process NOTE Due to its high work-hardening rate the steel reaches high uniform elongation values and high tensile strength levels 3.8 CP (complex-phase) steel steel with a ferrite/bainite matrix containing small amounts of martensite, retained austenite and or pearlite NOTE An extreme grain refinement is caused by retarded recrystallisation or precipitation of micro-alloying elements
3.9 MS (martensitic) steel steel with a martensitic matrix containing small amounts of ferrite and/or bainite produced by thermomechanical rolling
NOTE Within the group of multiphase steels the MS steels show the highest tensile strength level 3.10 coating mass total mass of coating (expressed in grams per square metre) given for both surfaces in the case of Z or ZF coating and separately for each surface in the case of ZE or ZN coating (see 7.3.5)
NOTE The nominal coating mass is used as coating designation in the case of hot dip coated products (Z, ZF). For electrolytically coated products (ZE, ZN), the coating thickness is
