JFE Steel has developed two kinds of 780 MPa class steel tubes for automotive suspension parts. They have excellent formability, fatigue endurance, toughness and paintability. In addition to the material development, tube forming and its evaluation techniques are also important for applying high strength steel tubes to actual parts. The effects of forming conditions and mechanical properties on formability in bending, nosing and hydroforming are also discussed. (Engl. translation from JFE GIHO, 2004, No.4, p.28-32, (jap.))
