Corrosion Resistance 
Really good corrosion resistance with regard to organic and natural substances, oxidating options, foodstuff, sterilizing remedies. Excellent 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 remedies. AISI 302 displays a bit ideal corrosion resistance with regard to AISI 304/304L stainless steels.


Property  Description
Hardness* Balls can be equipped in the (1) Chilly Worked (HRC twenty-39, common merchandise) or (two) ANNEALED (HV 100-250, on demand from customers) conditions.
Magnetism Eventual magnetism of AISI 316 balls and in basic of all austenitc stainless steels strictly is dependent by the production method, particular inquiries for not magnetic balls ought to priorly reported.
Precision Grade** On specifical request and for large quantities, we can provide G10 and G16 precision grade balls. Diameters from three.000 mm to 1/2″.
Precision Quality** On specifical request we can source G20-24-25-28-forty-forty eight-fifty-60-80 precision grade balls.
