AISI 430 / 430F Stainless Steel Balls
Stainless Steel balls are ferritic and unhardened in nature, these balls show good mechanical and corrosion resistance features which are considered to be superior to the martensitic stainless steel. As a standard practice at the Tolia group all stainless steel balls are supplied in a passivated condition.
Applications :
- Cosmetic nail polish
- Cosmetic balls
- Heat Exchangers
- Ball for valves
- Sprayers
- Automotive Industry
