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


Property  Description
Hardness* Balls can be provided in the (1) Cold Worked (HRC 20-39, standard product) or (2) ANNEALED (HV a hundred-250, on need) problems.
Magnetism Eventual magnetism of AISI 316 balls and in common of all austenitc stainless steels strictly is dependent by the production method, particular inquiries for not magnetic balls ought to priorly documented.
Precision Quality** On specifical ask for and for big portions, we can source G10 and G16 precision quality balls. Diameters from three.000 mm to one/two”.
Precision Quality** On specifical request we can offer G20-24-25-28-40-forty eight-fifty-sixty-eighty precision quality balls.
