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


Property  Description
Hardness* Balls can be provided in the (1) Cold Worked (HRC twenty-39, regular product) or (2) ANNEALED (HV a hundred-250, on demand) conditions.
Magnetism Eventual magnetism of AISI 316 balls and in common of all austenitc stainless steels strictly is dependent by the production procedure, particular inquiries for not magnetic balls ought to priorly documented.
Precision Quality** On specifical ask for and for massive portions, we can supply G10 and G16 precision grade balls. Diameters from three.000 mm to 1/2".
Precision Quality** On specifical request we can source G20-24-25-28-forty-forty eight-50-sixty-80 precision quality balls.
