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


Property  Description
Hardness* Balls can be supplied in the (one) Chilly Labored (HRC 20-39, common merchandise) or (two) ANNEALED (HV a hundred-250, on need) circumstances.
Magnetism Eventual magnetism of AISI 316 balls and in basic of all austenitc stainless steels strictly relies upon by the manufacturing method, particular inquiries for not magnetic balls must priorly documented.
Precision Quality** On specifical request and for big portions, we can source G10 and G16 precision quality balls. Diameters from three.000 mm to one/2″.
Precision Quality** On specifical ask for we can source G20-24-twenty five-28-40-forty eight-50-sixty-80 precision quality balls.
