The hot-dip galvanized steel HX260LAD in accordance with the EN 10346 standard (material number 1.0929) is a low-alloyed or micro-alloyed structural steel that achieves its outstanding mechanical properties through the targeted alloying additions of niobium, titanium and vanadium. These microalloys result in a fine-grained microstructure and enable a combination of high strength and good toughness. Hot-dip galvanizing in accordance with EN 10346 is carried out in a continuous immersion process in which the strip sheet is repeatedly passed through a liquid zinc bath and then cooled in a controlled manner. This creates a homogeneous, protective zinc layer that gives the steel long-lasting corrosion protection and makes it permanently resistant even under difficult environmental conditions.

HX260LAD is characterized by a balanced combination of strength, toughness and ease of processing. The micro-alloying elements cause precise grain refinement and a significant increase in the yield strength Rp0.2 to at least 260 N/mm² via fine precipitates. Typical tensile strengths are in the range of 350-430 N/mm² with an elongation at break A80 of at least 26 %. Thanks to its fine-grained structure and the harmonious interaction of niobium, titanium and vanadium, HX260LAD has a high impact strength, even at low temperatures, and is also easy to weld and form. The zinc coating prevents corrosion on the surface and helps to ensure that the key mechanical values are retained even after many years of use.

Due to its high strength and load-bearing capacity, HX260LAD is used in various industrial sectors. In the automotive industry, it is suitable for structural components such as cross members, reinforcements in the underbody and chassis parts where weight reduction and crash safety are required at the same time. In mechanical engineering, it is used in highly stressed machine frames and add-on parts that have to withstand dynamic forces. HX260LAD can also be used in commercial and structural engineering for slender steel frames, bridge girders or crane frames, where a combination of high load-bearing capacity and durability is crucial. Pipelines and sectional steels also benefit from the microalloying, as it ensures improved fatigue strength and uniform deformation even under changing loads.

Hot-dip galvanized steel HX260LAD in accordance with EN 10346 combines a fine-grained microstructure with high strength and excellent corrosion protection thanks to the micro-alloyed alloy with niobium, titanium and vanadium. The combination of a yield strength of around 260 N/mm², a tensile strength of up to 430 N/mm² and a reliable zinc coating makes HX260LAD an economical and technically mature solution for demanding applications in the automotive industry, mechanical engineering, building and bridge construction as well as in tube and profile technology. Manufacturers benefit from high process reliability, reduced material thicknesses and long-term durability of their components.
