Applications of stainless steel to automotive parts for lighter weight and higher durability, ultimately contributing to environmental protection, have been increasing. Kawasaki Steel has developed a new forming process and a mill. This mill was termed CBR (chance-free bulge roll) forming mill that adopts a new design of a roll flower pattern. High quality ERW stainless steel pipe, which has excellent formability and high quality of welded seam, was satisfactorily produced by this mill. The average r-value of the newly developed stainless steel was improved by more than 1.3 times in comparison with the conventional stainless steel while retaining the same level of heat resistance. Therefore, the formability of the newly developed stainless steel pipes was nearly equal to that of conventional stainless steel pipes after stress relief annealing. (VDEh)
