KTM-D Sheet Steel with Superior Deep Drawability and Direct-on Enameling Property

摘要

Various types of enameling sheet steels have been developed by the continuous casting-continuous annealing process. However, it is difficult to produce sheet steels that combine deep-drawability and enameling properties suitable for direct-on enameling as in decar-burization-annealed rimmed steels made from ingots, and it has therefore been impossible to shift the material from ingot-cast steels to continuously cast, continuously annealed steels. Kawasaki Steel recently succeeded in developing KTM-D sheet steel that combines deep drawability and enameling properties using a boron-added medium-oxygen steel already produced by Kawasaki Steel.
