hot-dip galvanized microalloyed steel according DIN EN 10346
Furthermore our product portfolio includes hot-dip galvanized microalloyed steel. Under this designation, the grades HX160YD to HX500LAD are incorporated. Compared to soft hot-dip galvanized steel, these steel grades have good cold formability at a defined yield strength. The grades of steels are sorted by increasing values of yield strength. The bake hardening steels “B” have an increase in yield strength, with a heat exposure in the range of 170 ° C (holding time 20 min, pre-deformation of 2%) on. Through a controlled composition, the higher strength IF steels “Y” have improved r and n values. The microalloyed steels “LA” achieve the required yield strengths by alloying with one or more elements of Nb, Ti and V. For hot-dip coated strip and sheet, the following European uniform marks have been introduced.
- Z zinc coating (99% Zn)
- ZF zinc-iron alloy coating (Galvannealed)
- ZA zinc-aluminum coating (Zn + 5% Al)
- AZ aluminum-zinc coating (55% Al + 1.6% Si + Zn)
- AS aluminum-silicon coating (11% Si + Al)
- ZM zinc-magnesium coating (1-2% Mg + 1-2% Al + Zn)

Zinc coating finish – common zinc crystal (N)
This design results by an unaffected solidification of the zinc coating. Depending on the galvanizing conditions, either zinc crystals with different gloss and size or no zinc crystals may be present. The quality of the coating is not affected.
Zinc coating finish – small zinc crystal (M)
This design results by deliberately influencing the solidification process. The surface has a smaller zinc flower, which in some cases is not visible to the naked eye. If the usual zinc flower does not meet the requirements of the appearance of the surface, this design comes into consideration.
Coating design for zinc-iron alloy (ZF)
The coating of a zinc-iron alloy in a usual condition is formed by a heat treatment in which iron diffuses through the zinc. The surface has a uniform matt gray look.
Coating design for zinc-aluminum coatings (ZA)
An unaffected solidification of the zinc-aluminum coating results in this version with a metallic luster. Depending on the manufacturing conditions, crystals of different gloss and of different sizes are formed. The quality of the coating is not affected.
Coating design for zinc-magnesium coatings (ZM)
By an unaffected solidification of the zinc-magnesium coating, this version results in a different appearance, from dull to metallic sheen. Possible images and a tendency to darken may occur.
Coating design for aluminum-zinc coatings (AZ)
The products are delivered with standard crystals. Common crystals are a version with metallic luster, which results in unaffected growth of aluminum-zinc crystals under normal solidification conditions.
Coating design for aluminum-silicon coatings (AS)
In contrast to the other hot-dip coated products, a relatively pronounced Al-Fe-Si alloy layer is formed on the base material during hot dipping. This must be taken into account in further processing steps.
Details of the mechanical values can be found in the table above. In addition, you can download the complete excerpt of our Quality Guides (QG) on the hot-dip galvanized microalloyed grades via the link. We can supply the steel grades described as coil, slitted coil, sheets and blank.
