Ultra-low-carbon interstitial free (IF) steel sheets bearing Ti and/or Nb have been extensively used for automotive panels because of superior formability and nonaging properties. It is well known that the interstitial elements such as C and N play important roles in the formability. The lower the contents of the C and N in steel, the better the formability of the steel. The demands for the steel with excellent formability from automotive industry will accelerate the progress in the steelmaking process, leading to the development of the ultra-low-carbon steel. With the advent and installation of improved vacuum degassing equipment in the steelmaking process, it is now possible to consistently produce ultra-low-carbon content of 0.002 to 0.005 wt pct. It is expected that in the near future, the C and N contents can be lowered to as low as 0.001 pct or less. This study is focused on strength and formability in the extremely ultra-low-carbon IF steels containing about 0.001 pct carbon.
