Description
Summary:Kawasaki Steel Corporation has developed a new steel tube making process which includes warm-reducing after the electric resistance welding of steel strip. The tube properties such as bending, fatigue and torsion etc. can be improved by a warm-reducing process due to refining microstructure, spheroidizing cementite and improving texture. In this report, we present the metallurgy and the fundamental characterisitics of developed steel tubes. Furthermore, the practical characteristics and some application examples of the developed steel tubes to automotive parts are introduced.
