316 Stainless steel balls provide resistance
to sulfurous acid compounds and other highly corrosive
environments. 316 Stainless Steel is used in the presence
of sulfuric, phosphoric, and acetic acids. 316 is the
least magnetic of the 300 series. Ask us about our special
packaging for surface protection.

420 B & 420 C Stainless Steel: Due to the
high hardness together with the good resistance against
corrosion makes the balls made in this material suitable
for valves, special bearings and so on, in which the
protectionwith rustproof-greases is poor or absent.
