Steels are increasingly utilized in new vehicle generations, which require both high strength and good formability. Dual-phase steels meet this objective particularly well.
Thanks to a component-appropriate design and a reduction of the material thickness, this new generation of materials makes considerable contributions to lightweight automotive engineering and construction.
StronSal® MC was developed by Salzgitter Flachstahl in order to achieve better corrosion protection compared to conventional zinc coatings - the unique composition of the coating significantly improves the corrosion resistance of the steel.
In the cut edge corrosion test according to VDA 621-415, StronSal® MC demonstrates corrosion resistance which is at least twice as high as that of conventional zinc coatings.
As a producer of high-quality flat products, Salzgitter Flachstahl is demonstrating the fact that weight reductions can also be achieved by reducing the coating thickness and deploying the newly developed hot-dip coating StronSal®. Since StronSal® contains - in addition to zinc - 1-2 percent magnesium and aluminum, the coating delivers excellent anti-corrosive properties despite reduced layer thickness.
The StronSal® surface is used in e.g. dual-phase steel fenders.
