These balls are non hardenable austenitic stainless steel with titanium which allow the balls to guarantee a better corrosion resistance in comparison to the AISI 304L & AISI 316L materials. As a standard practice at the Tolia group all stainless steel balls are supplied in a passivated condition.
Applications :
- Special pumps
- Ball Valves
- Food Industry
- Pharma Industry
