In 1952, TISCO and Fushun Special Steel, etc. produced stainless steel, ending the history of China's inability to produce stainless steel. In December 1970, TISCO produced cold-rolled stainless steel sheets.   In September 1983, the first domestically made 18-ton argon-oxygen external refining furnace (AOD) produced the first furnace of ultra-low carbon stainless steel in TISCO.
