Ferritic stainless steels have a body-centered cubic crystal structure, are magnetic, and are hardenable by cold working, but not by heat treating. They contain between 10.5% and 27% chromium with very little or no nickel. Due to the near-absence of nickel, they are less expensive than austenitic stainless steels. Representative alloys include Type 409, Type 429, Type 430, and Type 446. Ferritic stainless steels are present in many products, which include:

  • Architectural and structural applications[2]
  • Building components, such as slate hooks, roofing, and chimney ducts[citation needed]
  • Power plates in solid oxide fuel cells operating at temperatures around 700 °C (1,300 °F)[3]
