Corrosion Resistance 
Quite good corrosion resistance with respect to organic substances, oxidating remedies, foodstuff, sterilizing remedies. Very good resistance with respect to atmospheric corrosion and dyes. They are subjected to pitting and crevice corrosion in presence of sizzling chloride options and to anxiety corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid solutions. AISI 302 exhibits somewhat very best corrosion resistance with respect to AISI 304/304L stainless steels.


Property  Description
Hardness* Balls can be supplied in the (1) Cold Worked (HRC twenty-39, common product) or (2) ANNEALED (HV 100-250, on demand from customers) problems.
Magnetism Eventual magnetism of AISI 316 balls and in general of all austenitc stainless steels strictly is dependent by the manufacturing procedure, certain inquiries for not magnetic balls should priorly noted.
Precision Quality** On specifical ask for and for huge portions, we can provide G10 and G16 precision grade balls. Diameters from three.000 mm to 1/2″.
Precision Grade** On specifical ask for we can provide G20-24-25-28-forty-48-50-sixty-eighty precision quality balls.
