Corrosion Resistance 
Really very good corrosion resistance with regard to natural and organic substances, oxidating answers, foodstuff, sterilizing remedies. Good resistance with regard to atmospheric corrosion and dyes. They are subjected to pitting and crevice corrosion in existence of scorching chloride options and to stress corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid remedies. AISI 302 exhibits a bit ideal corrosion resistance with respect to AISI 304/304L stainless steels.


Property  Description
Hardness* Balls can be supplied in the (1) Cold Labored (HRC twenty-39, standard merchandise) or (two) ANNEALED (HV a hundred-250, on need) situations.
Magnetism Eventual magnetism of AISI 316 balls and in basic of all austenitc stainless steels strictly depends by the production procedure, particular inquiries for not magnetic balls need to priorly reported.
Precision Quality** On specifical request and for huge portions, we can offer G10 and G16 precision grade balls. Diameters from three.000 mm to one/2″.
Precision Grade** On specifical ask for we can provide G20-24-25-28-forty-48-50-sixty-eighty precision grade balls.
