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


Property  Description
Hardness* Balls can be equipped in the (one) Cold Worked (HRC twenty-39, normal item) or (2) ANNEALED (HV 100-250, on demand) situations.
Magnetism Eventual magnetism of AISI 316 balls and in common of all austenitc stainless steels strictly depends by the manufacturing procedure, distinct inquiries for not magnetic balls need to priorly noted.
Precision Grade** On specifical request and for big portions, we can provide G10 and G16 precision quality balls. Diameters from 3.000 mm to one/two”.
Precision Quality** On specifical ask for we can supply G20-24-twenty five-28-40-48-50-60-eighty precision quality balls.
