JFE Steel has developed two types of high performance high-strength steel sheets for automobile body exposed panels to reduce the weight of automobile body panels. 1) The SFG (super fine grain) HITEN, 'SFG HITEN', which is strengthened by fine grains, gives excellent press-formability with low yield strength and a large r-value. It is observed that the formation of PFZs (precipitate free zones) results in a mechanism in which yielding begins at low stress at an initial deformation stage. SFG HITEN is expected to be applied to side outer panels. 2) The UNI (uniform unique universal) HITEN, 'UNI HITEN' as a low YR, 440 MPa grade BH steel sheet with excellent surface quality, a high yield strength, excellent press-formability and high dent-resistance obtained by paint baking after press-forming, and good potential for gauge reductions as a consequence. UNI HITEN is expected to be applied to door, hood and trunk-lid. (English translation from JFE Giho, No 16 (2007), P. 12-15 (jap.)).
