Corrosion Resistance 
Extremely great corrosion resistance with regard to natural substances, oxidating answers, foodstuff, sterilizing options. Excellent resistance with respect to atmospheric corrosion and dyes. They are subjected to pitting and crevice corrosion in presence of hot chloride answers and to pressure corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid options. AISI 302 shows marginally best corrosion resistance with respect to AISI 304/304L stainless steels.


Property  Description
Hardness* Balls can be equipped in the (1) Cold Labored (HRC 20-39, regular merchandise) or (two) ANNEALED (HV a hundred-250, on need) problems.
Magnetism Eventual magnetism of AISI 316 balls and in common of all austenitc stainless steels strictly relies upon by the production process, particular inquiries for not magnetic balls ought to priorly reported.
Precision Grade** On specifical ask for and for massive quantities, we can offer G10 and G16 precision grade balls. Diameters from three.000 mm to one/two”.
Precision Quality** On specifical request we can provide G20-24-twenty five-28-forty-48-50-60-80 precision grade balls.
