Series , Low-Carbon Ferritic Type 405 12-13 Chromium

1 Chromium Steels (400 Series), Low-Carbon Ferritic (Type 405) 12-13% Chromium 

The main use of this type steel is for situations in which the process material may not be corrosive to mild steel, yet contamination due to rusting is not tolerable and temperatures or conditions are unsuitable for aluminum. However, prolonged use of these steels in the temperature range of 450 to 550°C causes low-temperature embrittlement of most ferritic steels with more than 12% chromium [16].
