Corrosion Resistance 
Quite good corrosion resistance with regard to organic and natural substances, oxidating options, foodstuff, sterilizing remedies. Great resistance with regard to atmospheric corrosion and dyes. They are subjected to pitting and crevice corrosion in presence of scorching chloride remedies and to pressure corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid solutions. AISI 302 displays somewhat best corrosion resistance with regard to AISI 304/304L stainless steels.


Property  Description
Hardness* Balls can be supplied in the (1) Cold Labored (HRC twenty-39, regular item) or (two) ANNEALED (HV 100-250, on need) situations.
Magnetism Eventual magnetism of AISI 316 balls and in standard of all austenitc stainless steels strictly depends by the production approach, particular inquiries for not magnetic balls must priorly noted.
Precision Quality** On specifical request and for big quantities, we can offer G10 and G16 precision quality balls. Diameters from three.000 mm to one/2″.
Precision Grade** On specifical request we can supply G20-24-twenty five-28-forty-forty eight-50-sixty-eighty precision quality balls.
