Abstract: Main equipments and production process of No.2  Steelmaking Plant of  TISCO are briefly introduced in this paper. The progress in reducing cost and improving production efficiency was discussed. The specification of 400 series stainless steels steelmaking process in TISCO is using hot metal as the major materials, which is apt to produce superferritic stainless steels. The process used in TISCO need lower cost than traditional process which using waste steels as major materials. The specification of 300 series stainless steels steelmaking process in TISCO is using pig iron consisted of chromium and nickel as the major materials. The dosage of pig iron reaches 625 kg/t which is at the advanced level throughout China.

Key words: stainless steel, steelmaking, low cost
