400 series stainless steels
FERRITIC STAINLESS STEELS
This group of ferritic stainless steels (400 series) contain 10.5% to > 30% chromium for corrosion scaling at elevated temperatures and resistance. They are non-hardenable by heat treating, and always magnetic. Ferritic stainless steel is used in applications where resistance to corrosion and oxidation is important. The lower chromium (11%) ferritics are primarily used for automotive exhaust. Ferritics with intermediate chromium contents (15 – 17%) are used for automotive trim, hot-end automotive exhaust, appliances, and cooking utensils. The high-chromium ferritics (18 – 30%) are used in automotive exhaust, trim, and appliance applications requiring high oxidation and corrosion resistance |
MARTENSITIC STAINLESS STEELS
These steels, of the 400 series, usually contain a minimum of 11.5% up to 18% chromium and have higher levels of carbon than ferritics. They are capable of being heat treated to a wide range of useful hardness and strength levels, and are used extensively in cutlery, sports knives, multipurpose tools, and structural parts. |
