Corrosion Resistance 
Extremely good corrosion resistance with regard to organic and natural substances, oxidating answers, foodstuff, sterilizing solutions. 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 answers. AISI 302 shows slightly greatest corrosion resistance with regard to AISI 304/304L stainless steels.


Property  Description
Hardness* Balls can be provided in the (1) Cold Worked (HRC 20-39, common solution) or (2) ANNEALED (HV a hundred-250, on need) problems.
Magnetism Eventual magnetism of AISI 316 balls and in general of all austenitc stainless steels strictly depends by the producing procedure, specific inquiries for not magnetic balls ought to priorly noted.
Precision Quality** On specifical ask for and for huge portions, we can source G10 and G16 precision grade balls. Diameters from 3.000 mm to one/2″.
Precision Quality** On specifical request we can supply G20-24-twenty five-28-forty-48-fifty-sixty-80 precision grade balls.
