AISI 420-B /420-C
AISI 420-B /420-C (MARTENSITIC)It is an appropriate stainless steel for applications in contact with water, steam and gasoline. Due to their chemical composition, the balls are able to be hardened, obtaining a lightly lower hardness to the chrome steel AISI 52100. They are very used in applications like valve, stainless bearings, polishing machinery (as mill element)
