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


Property  Description
Hardness* Balls can be supplied in the (one) Chilly Worked (HRC twenty-39, regular item) or (2) ANNEALED (HV a hundred-250, on demand from customers) conditions.
Magnetism Eventual magnetism of AISI 316 balls and in common of all austenitc stainless steels strictly is dependent by the production approach, specific inquiries for not magnetic balls must priorly described.
Precision Grade** On specifical ask for and for big quantities, we can provide G10 and G16 precision grade balls. Diameters from three.000 mm to one/two”.
Precision Grade** On specifical request we can source G20-24-twenty five-28-40-48-fifty-60-80 precision quality balls.
