Development of ferritic stainless steel sheets with excellent deep drawability by (111} recrystallization texture control

摘要

In order to develop ferritic stainless steel sheets with high formability, control of the {111} recrystallization texture has been investigated with the aim of increasing the Lankford values. Based on the results, development of ferrite stainless steel with deep drawability which has an r-value of the highest level in the world has been achieved. The newly developed ferritic stainless steel is expected to be applied in a wide range of automotive parts, and applications requiring corrosion resistance and deep drawability, in which SUS304 or high strength steel with corrosion protection treatment has been used.
