The hot-dip galvanized steel HX300LAD in accordance with the EN 10346 standard is a high-performance micro-alloyed structural steel that has been specially developed for use in highly stressed structural applications. Under the material number 1.0932, HX300LAD combines the advantages of a specific micro-alloy with niobium, titanium and vanadium with the proven corrosion protection of homogeneous hot-dip galvanizing. Thanks to its fine-grained microstructure, which is due to the precipitation of finely dispersed carbides and nitrates, this steel achieves a significantly increased yield strength and tensile strength combined with good toughness and workability.

HX300LAD impresses with its balanced combination of the following mechanical and technological characteristics:

In addition, HX300LAD is characterized by a homogeneous microstructure, good weldability and excellent dimensional stability, which enables economical further processing in cutting, bending and welding processes.

Thanks to its high strength, toughness and reliable corrosion protection, HX300LAD is mainly used in the automotive industry. Typical areas of application are

The hot-dip galvanized steel HX300LAD in accordance with EN 10346 combines an excellent combination of high strength, good ductility and long-lasting corrosion protection thanks to the micro-alloying with niobium, titanium and vanadium. With a minimum yield strength of around 300 N/mm², a tensile strength of up to 600 N/mm² and an elongation at break of at least 16 %, it offers a technically and economically mature solution for demanding structural components in the automotive industry. The flexible selection of coating alloys also enables precise adaptation to a wide range of environmental and operating conditions – a decisive advantage for modern vehicle concepts that have to combine lightweight construction, safety and durability.
