Material characteristics
Due to its selected chemical composition and special hot-rolling process, complex-phase steel has an extremely fine microstructure. In the complex interaction of matching microstructure components and precipitation hardening, this results in a particularly attractive combination of properties: high strength and wear resistance with good cold formability and weldability.
Heat treatment
Heat treatmet of hot-rolled complex-phase steels at temperatures from 500 to 700°C can be used to increase the yield strength by up to 100 MPa (e.g., 680°C, dwell time 0.7 min/mm sheet thickness in saline bath). In addition, forming in the temperature range from 550°C to 650°C enables complex parts to be produced without compromising the component properties.
