EN-Product-Metallic coated-All Grades Coatings Surface aspectsTSUK

Coatings and surface aspects

Coatings

Three types of metallic coating are available:

Pure zinc

Galvanised steel (Z/GI) is coated with an almost pure zinc coating (>99% zinc).

Zinc-iron alloy

Produced in the Netherlands. For further information click here.

MagiZinc

MagiZinc steel (ZM) is coated with a zinc coating containing additional magnesium and aluminium.

Coating weight

Coating	Minimum	Maximum
Pure zinc (Z/GI)	90 (6 µm/side)	275 (20 µm/side)
MagiZinc (ZM)¹	70 (5 µm/side)	310 (22 µm/side)

Coating weight measured in g/m² double-sided (µm, per side).

Surface quality

Surface quality complies with standard: EN 10346:2015. Galvanised steels are available in surface quality A, B or C.
Also, Serica FLO^®surface quality produced in the Netherlands. For further information click here.

Surface quality A: as coated surface

Imperfections such as pimples, marks, scratches, pits, variations in surface appearance, dark spots, stripe marks and light passivation stains are permissible.
Stretch levelling breaks or run-off marks may appear. Coil breaks and stretcher strains may also appear.

Surface quality B: improved surface

With this surface quality, small imperfections such as stretch levelling breaks, skin pass marks, slight scratches, indentations, surface structure, zinc run-off marks and light passivation stains are permissible.

Surface quality C: best quality surface

Surface condition C is obtained by skin passing. The controlled surface for the exposed side enables application of a uniform paint finish. The reverse surface has, at least, the characteristics of surface quality B.

Surface finish

Pure zinc

MA: minimised spangle, as coated surface (Z/GI).
MB: minimised spangle, improved surface (Z/GI).
MC: minimised spangle, best quality surface (Z/GI).

MagiZinc^®

A : as coated surface (ZM).
B : improved surface (ZM).
C: best quality surface (ZM).

Surface roughness

Metallic coated steel (with the exception of galvanised steel with standard surface (MA) can be supplied in various grades of roughness – please contact us for more details. If no roughness is specified, roughness will be as shown in the table below.

Roughness Ra (µm)
cut off 0.8mm	cut off 2.5mm
0.6 - 1.9	0.7 - 2.2

Surface treatments

The surface treatments available are O, C and CO.

Oiling (O)

The material surface can be oiled with preservative oil. Other types of oil - for increasing strength or reducing weight – are available to help achieve your optimum performance parameters. Please contact us for details.

Tata Steel offers the following range of oiling levels:

Coating type	Capability
Pure zinc (Z/GI)	0.5 - 1.6 g/m²
MagiZinc^® (ZM)	0.5 - 1.6 g/m²

Other oiling levels are available on request.

Chromium-free passivation (C)

This surface treatment temporarily protects the zinc-coated material against white rust during transportation and storage (not applicable to all qualities and dimensions – please contact us for details).

Chromium-free passivation and oiled (CO)

Please request this combination of surface treatments if you require extra protection against white rust formation (not applicable to all qualities and dimensions – please contact us for details).

T-treatment

Please contact us for further information.

Prime Lubrication Treatment (PLT)

Prime Lubrication Treatment facilitates the manufacturing of stamped components by minimising known issues in stamping and joining.
Currently Under development, please contact us regarding further information

Untreated (U)

Please contact us regarding the availability of untreated coils.

EN-Product-Metallic Coated-HSS-HX300BD-Properties TSUK

Properties

Mechanical properties

Metallic coated high-strength steel grades have the following mechanical properties (skin-passed) - these are measured transverse to the rolling direction. Property range is indicated according to EN 10346, but properties meet equivalent VDA 239-100 specifications also.

Bake-hardening steels

	Grade	HX300BD
Yield strength R_eL	N/mm²	300 - 360
Min. BH2	N/mm²	30
Tensile strength R_m	N/mm²	400 - 480
Elongation	%	26
Min. r-value r₉₀		-
Min. n-value n₉₀		-

Lower yield strength or 0.2% proof stress applies.
BH2 refers to the increase of 0.2% proof stress after heating (bake hardening). Not applicable for hot rolled substrate.
Elongation after fracture A uses test piece length L₀ = 80 mm.

Chemical composition

Tata Steel supplies the following cast analysis with maximum values unless otherwise shown:
