AISI 420 Stainless Steel Balls

AISI 420 Stainless Steel Balls

AISI 420 Stainless Steel Balls

These balls are martensitic in nature and they have a good corrosion resistance. As a standard practice at the Tolia group all stainless steel balls are supplied in a passivated condition.

Applications :
  • These balls are used in various applications and are used as a cheaper alternative to the AISI 420C material.
