440SS (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.
