The 400 series includes both ferritic and martensitic steels.

Ferritic steels: non-hardening steels,  ideal for conditions in elevated temperatures. Typical applications for ferritic stainless steels include petrochemical, automotive exhaust systems, heat exchanges, furnaces, appliances and food equipment to name a few.

Martensitic steels: able to be hardened, ideal for a wide variety of common uses. Martensitic stainless steels are used extensively in cutlery, sport knives and multi-purpose tools.

 

Advantages and Characteristics of 400 Series Stainless Steel

Ferritic, or nonhardenable stainless steels, are classified in the 400 series. This series is known for:

  •  superior corrosion resistance
  • resistance to scaling at elevated temperatures
  • inherent strength greater than carbon steels
  • provide an advantage in many applications where thinner materials and reduced weight are necessary
  • nonhardenable by heat treating
  • always magnetic

Martensitic, or hardenable stainless steels, are classified in the 400 series. This series is known for:

  • higher levels of carbon than ferritics
  • ability to be heat treated to a wide range of hardness and strength levels
  • excellent corrosion resistance
  •  easily machined
  • good ductility
