400 SERIES STAINLESS
The 400 series group of stainless steels has an 11 percent chromium and 1-percent manganese increase, above the 300 series group. The 400 series is susceptible to rust and corrosion under some conditions. Heat-treating will harden the 400 series. The 400 series of stainless steels have higher carbon content, giving it a martensitic crystalline structure. This provides high strength and high wear resistance. Martensitic stainless steels aren’t as corrosion resistant as the austenitic types
Application of 400 Series Stainless Steel Plate
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.
The table below shows common types of 400 series steel:
| 400 Series Applications | |
|---|---|
| Type 405 | a ferritic steel, used especially for welding applications |
| Type 408 | heat-resistant; poor corrosion resistance; 11% chromium, 8% nickel. |
| Type 409 | cheapest type; used for automobile exhausts; ferritic (iron/chromium only). |
| Type 410 | martensitic (high-strength iron/chromium). Wear-resistant, but less corrosion-resistant. |
| Type 416 | easy to machine due to additional sulfur |
| Type 420 | Cutlery Grade martensitic; Excellent polishability. |
| Type 430 | decorative steel, used for automotive trim; ferritic. Good formability, but with reduced temperature and corrosion resistance. |
| Type 440 | a higher grade of cutlery steel, with more carbon in it, which allows for much better edge retention when the steel is heat-treated properly. |
| Type 446 | For elevated temperature service |
Ferritic, or nonhardenable stainless steels, are classified in the 400 series. This series is known for:
Martensitic, or hardenable stainless steels, are classified in the 400 series. This series is known for:
