420 Stainless Steel Ball is a martensitic stainless steel ball with 12% Chromium which is sufficient to give good corrosive resistance properties. .It's best corrosive resistance is when hardened and surface is ground or polished. It has good ductility in the annealed condition but can be hardened up to 500HB (highest of the chromium grades) due to its excellent harden-ability, it is capable of getting hardened up to 50 HRC Rockwell or higher. Martensitic Grades are known for high hardness and allowances must be made for poor weld ability and usually allowances for a final harden and temper treatment. 420 steel is magnetic and welding is not recommended. Material will not pass the 72 hours salt bath test.
440c stainless steel ball

they can be provided in the annealed, cold worked, hardened, magnetic or not magnetic state. The wide variety of steels allows to choose the right material when high corrosion resistance or hardness or mechanical/wear and abrasion resistance properties are demanded.
