Ferritic-bainitic steel “F”
Ferritic-bainitic steels: A material with two faces
In the world of steels, ferritic-bainitic steel, or FB steel for short, occupies a special position. It combines two opposing iron crystals in its microstructure: ferrite, soft and ductile, and bainite: hard and tough. This unique combination gives it properties that set it apart from conventional steels.
A play of opposites:
Ferrite, the main component of FB steel, ensures its good ductility. It can be bent and shaped without breaking, making it ideal for applications that require flexibility. Bainite, on the other hand, distributed in the form of fine needles in the ferrite matrix, brings extreme strength and toughness into play. This synergistic combination creates a material that is both strong and malleable.
Versatility knows no bounds:
The outstanding properties of FB steel open up a wide range of possible applications. From heavy-duty load-bearing structures in bridges and buildings to delicate components in machines and vehicles – its versatility knows virtually no bounds. FB steel is also used in the offshore sector, where corrosion resistance and strength are crucial.
Welding without compromise:
Unlike many high-strength steels, FB steel can be easily welded without losing its strength and toughness. This property is a clear advantage in processing and enables the production of complex designs.
Lightweight with a heavyweight:
Despite its high strength, FB steel impresses with its comparatively low weight. A decisive factor in the automotive industry, where every gram counts, and in the aerospace industry, where weight savings improve flight performance and fuel consumption.
Research and innovation:
The development of FB steel is progressing steadily. Researchers are continuously working on further improving its properties and opening up new areas of application. The aim is to exploit the full potential of this material and make it an indispensable building block for the future of construction and manufacturing technology.

Dual-phase steel “X” (DP)
Dual-phase steel: a material of contrasts
Dual-phase steel (DP steel) occupies a fascinating special position in the world of steels. Its structure presents an exciting interplay of opposites: A soft, ferritic matrix forms the basis into which martensitic islands are embedded. This martensitic phase, as hard and strong as diamond, gives DP steel its exceptional strength and toughness.
Synergy of opposites:
The soft ferrite matrix ensures the ductility of the DP steel. It makes it possible to bend and shape it without it breaking. The hard martensitic islands, on the other hand, provide enormous strength and toughness. This interplay of seemingly contradictory properties creates a material that is both strong and malleable.
Unique properties:
This unique combination predestines DP steel for a wide range of demanding applications. Where the highest loads and dynamic stresses are the order of the day, it impresses with its extreme strength and toughness. At the same time, its good formability allows it to be used in complex constructions.
Versatility knows no bounds:
From heavy-duty components in machines and vehicles to safety-critical components in the aerospace industry – DP steel is used in a wide range of industries. Its versatility and potential make it an indispensable material for engineers and designers.
Innovation and further development:
The development of DP steel is constantly progressing. Researchers are constantly working on further improving its properties and opening up new areas of application. The aim is to exploit the full potential of this material and make it an even more important building block for the future of construction and manufacturing technology.

Complex-phase steel “C” (CP)
Complex-phase steel: a material full of possibilities:
Complex-phase steel (CP steel) occupies a special place in the fascinating world of steels. Its microstructure presents a complex interplay of different phases: Martensite and/or bainite, hard and strong like diamond, embedded in a matrix of ferrite and/or hardened ferrite. This unique microstructure gives CP steel properties that set it apart from other steels.
A play of phases:
The hard phases martensite and bainite give CP steel its extreme strength and toughness. They make it resistant to high loads and dynamic stresses. At the same time, the ferrite matrix ensures ductility and enables good formability of the material. This interplay of seemingly contradictory properties results in a material that is strong, tough and malleable at the same time.

From heavy-duty components in machinery and vehicles to safety-critical components in the aerospace industry – its versatility knows virtually no bounds. CP steel is also used in the offshore sector, where corrosion resistance and strength are crucial.
Challenge and innovation:
Due to its complex microstructure, the production of CP steel is more demanding than that of conventional steels. However, it is precisely this complexity that gives it the unique properties that make it so valuable. Continuous research and innovation lead to constant improvements in properties and the development of new areas of application.

This unique microstructure gives martensitic steel properties that predestine it for demanding applications.
Hardness and toughness combined:
The martensitic phase, as hard as diamond, gives martensitic steel its extreme strength and toughness. It makes it resistant to high loads and dynamic stresses. At the same time, the ferrite and/or bainite components ensure ductility and allow the material to be formed to a certain extent. This interaction results in a material that is strong, tough and malleable at the same time.

Zinc finish according to DIN EN 10346
Our zinc coatings are available in various designs that meet the specific requirements and aesthetic wishes of our customers:
Regular spangle (N): This design occurs when the zinc coating solidifies undisturbed. Depending on the galvanizing conditions, either no zinc flowers or zinc crystals with different gloss and size can occur. This variation does not affect the quality of the coating. If a pronounced zinc flower is desired, this should be specifically stated in the request and order.
Small spangle (M): This design is achieved by specifically influencing the solidification process. The surface has smaller zinc flowers, some of which are not visible to the naked eye. This variant is chosen if the regular zinc flower (see above) does not meet the requirements for the surface appearance.
Surface type according to DIN EN 10346
Regular surface (A)
With this surface type, certain irregularities are permitted which do not impair the quality and functionality. These include:
Stretch direction breaks and run-off waves can also occur, as can roll kinks and flow figures. Surface type (A) can be achieved both by cold rolling and without, whereby the choice of process is left to the manufacturer.
Improved surface (B)
With surface type B, it is produced by cold rolling. With this surface quality, the following irregularities are permitted to a small extent:
Bei der Oberflächenart B werden durch Kaltnachwalzen hergestellt. Bei dieser Oberflächenqualität sind in geringem Umfang folgende Unregelmäßigkeiten zulässig:
These features do not affect the functionality and quality of the end product and are a natural part of the cold rolling process.
Best surface (C)
Surface type C is produced by cold rolling. The tested side of this surface is specially suitable for a uniform quality paint finish. The reverse side meets at least the requirements of surface type B, which means that slight irregularities such as stretch direction breaks, dressing imprints and slight scratches are permitted.
Surface treatment and protection
When requesting and ordering our products, you can choose between different surface treatment conditions to meet specific requirements:
Note: The effect of the “oiled” surface protection is highly dependent on the atmospheric and storage conditions. Our products are usually supplied chemically passivated and/or oiled. At the express request of the customer, hot-dip coated products can also be supplied without surface treatment, but the responsibility for this lies with the customer.
Special requirements: If special transport and storage conditions require increased corrosion protection, the customer must inform the manufacturer accordingly when requesting and ordering. If the customer does not want oiled or chemically passivated surfaces, this must also be clearly stated in the request and order.
