Corrosion Resistance 
Quite very good corrosion resistance with regard to organic substances, oxidating options, foodstuff, sterilizing solutions. Good resistance with regard to atmospheric corrosion and dyes. They are subjected to pitting and crevice corrosion in presence of hot chloride solutions and to anxiety corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid options. AISI 302 exhibits somewhat greatest corrosion resistance with respect to AISI 304/304L stainless steels.


Property  Description
Hardness* Balls can be supplied in the (1) Chilly Worked (HRC 20-39, standard item) or (two) ANNEALED (HV one hundred-250, on demand) problems.
Magnetism Eventual magnetism of AISI 316 balls and in standard of all austenitc stainless steels strictly is dependent by the manufacturing approach, certain inquiries for not magnetic balls need to priorly documented.
Precision Quality** On specifical ask for and for massive portions, we can source G10 and G16 precision quality balls. Diameters from 3.000 mm to one/2″.
Precision Grade** On specifical ask for we can offer G20-24-25-28-40-forty eight-fifty-sixty-80 precision grade balls.
