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


Property  Description
Hardness* Balls can be supplied in the (1) Cold Labored (HRC 20-39, standard merchandise) or (2) ANNEALED (HV a hundred-250, on desire) 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 need to priorly described.
Precision Grade** On specifical ask for and for big quantities, we can source G10 and G16 precision grade balls. Diameters from 3.000 mm to one/two”.
Precision Grade** On specifical request we can offer G20-24-twenty five-28-40-48-fifty-60-eighty precision grade balls.
