Corrosion Resistance 
Very very good corrosion resistance with respect to natural substances, oxidating options, foodstuff, sterilizing remedies. Great resistance with respect to atmospheric corrosion and dyes. They are subjected to pitting and crevice corrosion in presence of scorching chloride options and to stress corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid options. AISI 302 demonstrates slightly ideal corrosion resistance with respect to AISI 304/304L stainless steels.


Property  Description
Hardness* Balls can be provided in the (1) Chilly Labored (HRC twenty-39, standard solution) or (two) ANNEALED (HV 100-250, on demand from customers) situations.
Magnetism Eventual magnetism of AISI 316 balls and in standard of all austenitc stainless steels strictly depends by the producing approach, distinct inquiries for not magnetic balls should priorly reported.
Precision Quality** On specifical ask for and for large portions, we can offer G10 and G16 precision quality balls. Diameters from three.000 mm to one/two”.
Precision Quality** On specifical request we can provide G20-24-twenty five-28-forty-48-50-60-eighty precision quality balls.
