420SS
(Stainless Steel Balls)
|
AISI
type 420 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 both bearing and valve
applications, as well as writing instruments and lighters.
