Stainless Steel Balls – Precision, Durability & Corrosion Resistance

Material: AISI 201/304/316/316L/420/440/440C
Diameter: 0.5mm-150.00mm;
Precision Grade:G5, 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.
