As a highly advanced and versatile material that has revolutionized the field of structural engineering, complex phase steel (CP) is used to provide exceptional strength and excellent formability, combining various alloying elements to create a microstructure with multiple phases. This unique composition leads to an impressive combination of mechanical properties, such as high tensile strength, excellent elongation and excellent resistance to deformation. These properties make CP steel a perfect option for demanding applications that require superior performance under extreme conditions. Nowadays, Docol 800 complex phase steel is increasingly used in automobile chassis parts as a main steel grade for manufacturing such parts.
