| Development of High Carbon HISTORY Steel
Tube with Excellent Formability Yoshikazu Kawabata, Takatoshi Okabe, Yasue Koyama |
| Synopsis : Kawasaki Steel has developed the HISTORY process as a next generation technology of manufacturing electric resistance welded steel tubes. Steel tubes with excellent properties can be produced by warm-reducing process which is put into practice in the HISTORY process for the first time in the world. In high carbon steel tubes, spheroiding of cementite that takes some hours in conventional annealing methods can be completed in several seconds by warm-reducing process. This effect of warm-reducing process makes it possible to produce high carbon steel tubes of excellent formability with high productivity. The high carbon HISTORY steel tube having excellent formability enables cold forming of complicated shapes and reduced working force in cold working. |
