Ideal for heavy loads

High-strength steel is a special category of steel that exhibits above-average strength and hardness compared to conventional steel thanks to special manufacturing processes and treatments.

These improved mechanical properties enable its use in demanding industrial applications where high load-bearing capacity, resistance to fatigue cracks or high resistance to mechanical stress are required.

Production, quality grades and applications of high-strength steel

To produce high-strength steel, a manufacturing process is required in which the metal is cooled, heated and/or reinforced under specific conditions to improve its hardness and strength. These process steps are carefully monitored to ensure that the end product meets the required specifications.

Depending on the process, different chemical compositions and heat treatments can be used to produce different grades and types of high-strength steel.

The quality grades of high-strength steel are defined according to DIN standards. Examples include hot-rolled fine-grained structural steel S700MC according to DIN EN 10149-2 or cold-rolled steels such as HC500LA according to DIN EN 10268. Each of these grades has specific properties and is suitable for different applications, depending on the specific requirements of the respective industry or its manufacturing sector.

High-strength steel is used in a wide range of sectors, e.g. in automotive engineering, mechanical engineering, profiling and pipe construction. Its hardness enables it to withstand loads that would be too intense for less robust types of steel. In addition, such steel offers added value for high-load applications due to its improved resistance to fatigue cracks and corrosion.
