JFE Steel has developed a new bending method (PRB) for thin-walled high strength steel tubes without a mandrel and a wiper in collaboration with Toyota Motor and Taiyo Corp. JFE Steel also developed the 780 MPa class electric-resistance-welded tubes (ERW tubes) for automotive suspension parts, and contributed to the realization of the development of the arm parts applying 780 MPa class ERW tubes. By eliminating the mandrel and the wiper, which wear out eventually and require long adjusting time, in the rotary draw bender, this new bending method enables the bending of the thin-walled high strength steel tube in high productivity as well as enabling the bending of the thin-walled high strength steel tube with irregular shape.
