Docol 1000CP Complex Phase Steel (CP) Description
Complex phase steel (CP) is a highly advanced and versatile material that has revolutionized the structural engineering field. CP steel can provide exceptional strength and excellent formability, combining various alloying elements to create a microstructure with multiple phases. This unique composition enables CP steel to have an impressive combination of mechanical properties, such as high tensile strength, excellent elongation and excellent resistance to deformation. These properties are highly needed for demanding applications that require superior performance under extreme conditions. In recent years, Docol 1000 complex phase steel is increasingly used in automobile chassis parts as a main steel grade for manufacturing such parts.
