STS400

STS400

  • The ferrite system consists of chromium, which has a low coefficient of thermal expansion and excellent corrosion resistance.
  • STS430 is the representative steel species, and by adding alloy components such as Ti, Nb, and Mo, steel species used for special purposes such as 409L and 430J1L have been developed.
