201stainless steel balls:
Cr-Mn stainless steel balls, with properties similar to AISI 302/304 balls
(slightly higher mechanical characteristics).
Balls are provided in the passivated condition.
304 stainless steel balls:
Unhardened austenitc stainless steel balls, they display good mechanical characteristics,
toughness and corrosion resistance.
AISI 304L provides lower carbon content, AISI 302 better mechanical characteristics.
Balls are provided in the passivated condition.
