440C

440C

440C is a high carbon chromium stainless steel that offers excellent performance in caustic plastic molds, rubber mold components, medical components, and much more.  440C has improved corrosion resistance compared to 420 ESR but lacks the machinability and polishability.  It is available in Plate and Round bar forms.
The optimal hardness range is 56-60 HRC.
