Blechexpo: it was nice
“EMPOWERING YOU“ is our trade fair motto.
We want to offer you exactly what you need for your work.
Be it the electromobility initiative selectrify®, process optimizations or processing support with the next generation of hot forming AS Pro or with our climate strategy – we are at your side.
Dual-phase steels with ZM Ecoprotect® for the outer skin
High strength, very good formability and increased crash safety with a thickness of only 0.55 millimeters? That's possible – with our dual-phase steel. This makes it ideal as an outer skin for lightweight vehicles.
Hot strip scalur® with very narrow thickness tolerances
Our scalur® hot-rolled pays off. There are more meters per coil thanks to the narrowest thickness tolerances.
Tinplate for goods in transit
Our tinplate is not only thinly rolled, but also electrolytically tinned. It is therefore particularly suitable as a packaging material for dangerous goods – regardless of whether they are transported by road, rail or sea.
Interview Dr. Arnd Köfler
tk Steel Chief Production Officer Dr. Arnd Köfler explains why climate protection is part of our corporate DNA. With our strategy, climate-neutral steel production is gradually becoming a reality. Now we have taken a further important step and used hydrogen instead of blow-in coal in the ongoing blast furnace operation. In our report you can see what the experiment looked like and what this means for the transformation to climate-neutral steel production.

Now we have taken another important step and are using hydrogen instead of blow-in coal in our ongoing blast furnace operations. You can see in our report what the experiment looked like and what this means for the transformation to climate-neutral steel production.
Our climate strategy
The target is clear: By 2050, steel production at thyssenkrupp must be climate neutral. With its climate strategy, the company is accelerating its initiatives to reduce emissions, promoting corporate social responsibility, and pledging its support for the Paris Climate Agreement of 2015.
selectrify® – the initiative for high-tech steel solutions in electromobility
Everybody's talking about electric mobility. The automotive industry is facing a radical change. We as one of the leading steel producers in Europe support this change by providing the suitable materials. Because e-mobility is unthinkable without steel.
smartgrind with powercore® electrical steel
We need flexible electrical networks to supply energy generated from renewable sources generating energy from renewable sources is not enough if the energy transition is to succeed; it also needs to be distributed sustainably. Although green energy generated from wind turbines and solar power systems is good for the environment, we can only be certain that this energy is distributed reliably if it can be fed into the transmission networks at a consistent frequency and voltage.
Our highlights at CWIEME 2019
CWIEME 2019 Empowering you was the motto at the end of May in Berlin. For three days thyssenkrupp Steel offered its customers exactly what they need for their work. And you can see what that was here. The leading trade fair for coil winding, insulation and electrical production takes place annually and is the meeting place for the transformer, electric motor and power generation industries throughout Europe.
It's a real high flyer: the delivAIRy® flying robot
TIS uses an autonomous drone, which transports samples from the different plants (power plant laboratory and raw material sampling in Schwelgern as well as blast furnace, OX etc.) by drone autonomously to the central laboratory for testing and analysis. From there, the drone collects these samples and brings them to the laboratory for testing.
Tinplate Circuit
Our materials cycle – a guaranteed closed loop. Many everyday products are made of tinplate. The advantage: They’re magnetic and therefore easy to sort out during garbage separation. This material is then reprocessed into new products at our factories – to be renewed again and again.
Steel Experience
In tandem with other materials steel is opening up previously unimaginable possibilities, as for instance e-mobility and numerous applications in the renewable energy sector.
But how is steel made? What happens in a blast furnace? And why are there 2,500 different kinds of steel?
You can find out all about this at our plant in Duisburg. We invite you to immerse yourself in the Steel Experience and witness advanced steel production at first hand. Our tour guides will tell you all about our production processes and our high-tech steel products and innovations.

scalur®+Z
Scalur+Z® is our hot-dip galvanized flat product with the tightest thickness tolerances for maximum efficiency in component production. It is used, for example, in container construction or in profiles and telescopic slides.
ZM Ecoprotect® for the best outer skin
thyssenkrupp Steel stands for the highest surface quality and offers all typical automotive coatings in the best outer skin quality. With ZM Ecoprotect® there is a zinc coating which is characterised by excellent processing properties and high corrosion protection.
Precision Steel is now called precidur®
From now on, you can recognize the best precision steel that we have ever offered at Hohenlimburg from these eight letters: precidur® stands for quality, the closest possible thickness and profile tolerances, short production cycle times, maximum flexibility, and highly competent support and service.
Water Cycle
Steel is like a soft-boiled egg. It needs to be immersed just right in water. And ideally, this water should be reused as often as possible.
Our technology is a learning opportunity
Stimulating an affinity for technology in young people is vital for our country's future. But unfortunately, school curricula don't offer much scope for such efforts.
Steel: top recycling rate
Many people dream of living forever. Our steel is living the dream. And this endows it with a decisive product advantage that ultimately makes it the valuable material it is.
Flawless finish
The Mini Hatch model made by BMW is an attractively bright and shiny presence on our streets. The high-quality ZM Ecoprotect® finish help to ensure that these cars remain that way over their entire lifespan.
Dual-phase steels - the new variety
A product range with so many options – thyssenkrupp’s dual-phase steels can be used in many ways.
Many criteria must be met if a company wants to be successful in the automotive industry, such as being environmentally friendly, conserving raw materials, and keeping costs low at all times. Yet demands placed on safety and comfort are rising. But it is not difficult to design lighter vehicles and make them affordable, as the Product Management area in thyssenkrupp’s Steel division has oriented its product range for cold-rolled dual-phase steels more toward the needs of customers and added new grades.
scalur®+Z: Precision savings!
In the 1.5 to 2 millimeter thickness range scalur®+Z displays a thickness tolerance of plus/minus 0.06 millimeters – literally a hair’s breadth. So, scalur®+Z saves weight – in shipping containers, cars or trucks. It is also suitable for low-roughness, high precision punched parts. Furthermore, a coil of scalur®+Z on average contains 60 meters more material which reduces retooling times at the customer’s plant.
ZM Ecoprotect®: Less is more!
Galvanized steel sheet is the basis for the production of cars – the “skin and skeleton” as it were.
By adding a small amount of magnesium to the zinc coating, engineers from thyssenkrupp’s steel division have made a big difference for the environment and customers: ZM EcoProtect conserves resources by allowing extremely thin coatings, enables presses and equipment to run longer thanks to lower abrasion, and extends the lifetime of car bodies.
New fabric filter for sinter plant
The filter is to go into operation in early 2017
At the end of 2015 thyssenkrupp’s steel division started construction of a further modern fabric filter in northern Duisburg. In the future it will further reduce dust emissions to make for an even better environmental situation in Duisburg.
Light and strong at 900°C
As soft as wax in the press.
Hot forming is an increasingly important process for high-strength steels Parts become harder or formable, whatever the design calls for – and lighter! The right combination of heating and cooling in the die produces customized material properties.
