HDT950C is a continuously hot-rolled hot-dip coated complex-phase steel specified in accordance with the DIN EN 10346 standard. This high-performance steel is characterized by a unique combination of high strength, outstanding ductility and excellent corrosion protection. These properties make it particularly suitable for demanding industrial applications, especially in automotive and mechanical engineering.

HDT950C is characterized by its complex microstructure consisting mainly of ferrite and bainite, supplemented by martensite, tempered martensite, retained austenite and pearlite. This multiphase structure enables the steel to withstand high mechanical loads while maintaining remarkable formability. The ferrite phase ensures good ductility, while the bainite and martensite phases increase the strength and hardness of the steel.

A special feature of HDT950C is the continuously hot-dip coated surface. By applying a layer of zinc during the hot-dip process, the steel is effectively protected against corrosion. This protective layer prevents oxidation and therefore significantly extends the service life of the steel, making it ideal for applications in corrosive environments.

HDT950C is widely used in the automotive industry, where high strength and corrosion resistance are crucial. It is often used in safety-critical components such as body structures and impact protection components. Its ability to absorb high mechanical loads while remaining malleable makes it a preferred choice for these demanding applications.

HDT950C is also used in mechanical engineering and the construction industry, where materials that are both robust and flexible are required. The steel’s good weldability and workability facilitate the production of complex components and contribute to the efficiency of manufacturing processes.

A key aspect of HDT950C is its classification as a complex-phase (CP) steel. These steels are characterized by their multiphase microstructure, which contains a combination of ferrite and bainite as the main phases and martensite, tempered martensite, retained austenite and pearlite as secondary phases. This structure gives CP steels an exceptional combination of strength and formability, which makes them attractive for numerous industrial applications.

Compared to other complex-phase steels such as HDT600C and HDT750C, HDT950C offers significantly higher strength. While HDT600C offers higher formability with lower strength and HDT750C has a balanced ratio of strength and formability, HDT950C stands for maximum strength. This property makes it ideal for applications that require high load-bearing capacity and resistance.

HDT950C is a continuously hot-rolled hot-dip coated complex-phase steel specified according to the DIN EN 10346 standard. Its complex microstructure and hot-dip coated surface give it an excellent combination of high strength, ductility and corrosion resistance. These properties make HDT950C an optimal choice for a wide range of industrial applications, particularly in the automotive, mechanical engineering and construction industries. The outstanding mechanical properties and extended corrosion protection contribute significantly to the reliability and efficiency of the components produced, making HDT950C an indispensable material for modern manufacturing processes.
