Ferritic Stainless Steel

Written by Jerry Ratzlaff. Posted in Stainless Steel

Ferritic steels contain trace amounts of nickel, 12-17% chromium, less than 0.1% carbon, along with other elements such as molybdenum, aluminum or titanium.


  • Magnetic
  • Non hardening by heat treatment
  • High ambient temperature strength
  • Resistant to chloride stress corrosion cracking
  • Subject to hydrogen embrittlement
  • Subject to ductile brittle temperature embrittlement
  • Low carbon grades easy to weld
