Corrosion Resistance 
Very excellent corrosion resistance with respect to natural substances, oxidating remedies, foodstuff, sterilizing solutions. Excellent resistance with respect to atmospheric corrosion and dyes. They are subjected to pitting and crevice corrosion in existence of sizzling chloride remedies and to stress corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid solutions. AISI 302 exhibits slightly very best corrosion resistance with respect to AISI 304/304L stainless steels.


Property  Description
Hardness* Balls can be supplied in the (1) Chilly Worked (HRC twenty-39, common item) or (two) ANNEALED (HV 100-250, on need) circumstances.
Magnetism Eventual magnetism of AISI 316 balls and in common of all austenitc stainless steels strictly depends by the producing procedure, specific inquiries for not magnetic balls must priorly described.
Precision Grade** On specifical ask for and for massive portions, we can source G10 and G16 precision quality balls. Diameters from three.000 mm to one/2″.
Precision Quality** On specifical request we can source G20-24-25-28-40-forty eight-50-60-80 precision quality balls.
