About 400-series stainless steels
Martensitic and ferritic stainless steels carry less nickel than the 300-series and remain magnetic. 410 and 420 are hardenable by quench and temper and are used for cutlery, shafts, and valve parts. 430 stays soft and is used for cosmetic trim and mild corrosion service. Compared to 300-series grades they trade general corrosion resistance for hardenability.
