AISI 302/304/304L Stainless Steel Balls
- Material: AISI 302/304/304L
- Diameter: 0.5mm-150.00mm;
- Precision Grade: G100, G200,G500,G1000
- Hardness: HRC 20-39
- Applications: Special bearings, pumps, horticultural and household sprayers, perfume miniature pumps, sprayers, valves for medical applications, etc. They are used in the aerospace, military, and food industries.
- Corrosion resistance: It has good corrosion resistance to organic matter, oxidation, bactericidal solutions, atmospheric corrosion, and dye performance. They are not resistant to sulphuric acid solutions. The corrosion resistance of AISI 302 is slightly better than that of AISI 304/304L stainless steel. Balls are provided under passivated conditions.
