Corrosion Resistance 
Really very good corrosion resistance with regard to natural substances, oxidating remedies, foodstuff, sterilizing remedies. Great resistance with regard to atmospheric corrosion and dyes. They are subjected to pitting and crevice corrosion in existence of very hot chloride remedies and to stress corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid answers. AISI 302 demonstrates slightly best corrosion resistance with respect to AISI 304/304L stainless steels.


Property  Description
Hardness* Balls can be supplied in the (one) Cold Worked (HRC twenty-39, normal product) or (2) ANNEALED (HV a hundred-250, on desire) circumstances.
Magnetism Eventual magnetism of AISI 316 balls and in basic of all austenitc stainless steels strictly relies upon by the producing procedure, specific inquiries for not magnetic balls should priorly noted.
Precision Quality** On specifical request and for large quantities, we can provide G10 and G16 precision quality balls. Diameters from 3.000 mm to 1/two”.
Precision Grade** On specifical request we can provide G20-24-twenty five-28-forty-forty eight-fifty-sixty-80 precision grade balls.
