440SS (Stainless Steel Balls)

440 Stainless Steel Balls

 

Stainless Steel Type 440 C Balls

AISI type 440-C stainless steel balls afford the advantage of maximum hardness combined with corrosion-resisting properties. This hardness, together with precise geometry and fine surface finish, makes them especially useful for bearing and valve applications where severe environmental conditions may occure.

Consumable electrode vacuum meleted (CEVM) and vacuum induction melted/vacuum arc remelted (VIM-MAR) materials are available upon request.

Mechanical Properties
Type 440-C steel balls are uniformly hardened and tempered throughout their entire diameter to achieve maximum strenght and quality.  Ball hardness is 58-65 Rockwell “C” as measured on parallel flat surfaces. Also, type 440-C stainless steel balls are magnetic. Custom heat treating is available for special hardness requirements.
