Corrosion Resistance 
Very good corrosion resistance with respect to natural and organic substances, oxidating answers, foodstuff, sterilizing answers. Good resistance with regard to atmospheric corrosion and dyes. They are subjected to pitting and crevice corrosion in existence of hot chloride answers and to stress corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid solutions. AISI 302 displays slightly 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 20-39, standard product) or (2) ANNEALED (HV 100-250, on demand) circumstances.
Magnetism Eventual magnetism of AISI 316 balls and in standard of all austenitc stainless steels strictly is dependent by the production method, particular inquiries for not magnetic balls ought to priorly noted.
Precision Quality** On specifical ask for and for large portions, we can source G10 and G16 precision quality balls. Diameters from three.000 mm to one/2″.
Precision Grade** On specifical request we can offer G20-24-25-28-forty-forty eight-50-60-eighty precision quality balls.
